The need for surge protection

Florida Light and Power 1999 Study — Sources of Facility Surge

and Overvoltage Events:

•ꢀ ~60% Internally Generated

•ꢀ ~40% Externally Generated

Causes and relevance of transients and surges

•ꢀ

Lightning strikes — Large scale impact, high current and

voltage, but least common occurrence.

•ꢀ

Power switching — Increasing occurrences:

•ꢀ Utility and customer load switching – Motors, large loads,

faults, capacitor banks, fuse and circuit breaker operation*, etc.

•ꢀ Source switching — Smart grid, gensets, photovoltaic power

systems and wind power generation, etc.

* During overcurrent events, both circuit breakers and fuses can produce arc

voltages 2-3 times the system voltage in accordance with the UL standards.

Today’s world is full of electronic products and electrical devices that

are susceptible to damage from overvoltage surges.

Damage caused by transients and surges

Surges caused by static discharge, capacitive and inductive loads or

lightning can quickly destroy sophisticated electronic equipment and

components used in industrial and commercial applications. These

surges cripple operations – particularly the data and communication

systems that virtually every enterprise relies upon today, including

UL^®508A panels with their reliance on control circuits.

•ꢀ

Disruptive – A voltage transient enters an electronic component

and it interprets the transient as a valid logic command, resulting

in system lock-up, malfunction, faulty output or corrupted files.

•ꢀ

Dissipative – Associated with short duration repetitive low energy

level surges, resulting in equipment failure over time including

electronic components, ballasts, motors and controllers, service

entrance equipment, panelboards and switchgear.

Also, the NEC requires a listed SPD to be installed on various

equipment types including elevators on emergency systems [NEC

620.51(E)], critical operations data systems (NEC 645.18), industrial

machinery with safety interlock circuits (NEC 670.6), wind electric

systems [NEC 694.7(D)], fire pump controllers (NEC 695.15),

emergency panelboards and switchboards (NEC 700.8) and critical

operations power systems (NEC 708.20).

•ꢀ

Destructive – Associated with high level energy surges, resulting

in immediate equipment failure including electronic components,

ballasts, motors and controllers, service entrance equipment,

panelboards and switchgear.

We offer a wide selection of Bussmann™ series surge protection

products that help assure power quality by eliminating damaging

surges.

applications

locations in 25 cities – 88.5% of AC power problems are transient

voltage related.

•ꢀ

2011 Erimar Systems Integration — A lightning strike entered the

metals fabricating facility and destroyed $20,000 worth of control

panels, electrical infrastructure and Cisco infrastructure. Loss of

data system also cost 11 days of production.

Internal damage — PCB destroyed by a surge

•ꢀ

IEEE Emerald Book and NFPA 780 both recommend using

surge protection as a part of a building’s lightning protection

system. Suppressors at the service entrance only reduce, but not

completely eliminate, the high-energy transient. A second surge

protective device must be applied upstream of critical equipment.

All SPDs should comply with UL 1449 4^thEdition or later.

Application Note 3193

Effective March 2019

694.7(D) “A surge protection device shall be installed between

a wind electric system and any loads served by the premises

electrical system.”

NEC surge protection requirements

In recent years, with the proliferation of electronics and devices

sensitive to transient voltage and current surges, the need for

surge protection has become increasingly important, particularly for

equipment and systems used for life safety or where reliability is

highly critical.

Added in 2011, surge

protective devices should

be on the circuit serving the

wind electric system or on the

service disconnect’s loadside.

The NEC recognizes this need and has adopted the following

provisions where surge protection is required.

Regardless of whether surge protection is required or not, it’s

prudent to have surge protection on all circuits as many portable

appliances and communications devices with sensitive electronics

may be powered from circuits where transient overvoltage surge is

an issue.

695.15 “A listed surge protection device shall be installed in or

on the fire pump controller.”

Added in 2017, this NEC

provision requires a listed SPD to

be installed in or on the fire pump

controller to provide protection. A

study commissioned by the Fire

Protection Research Foundation

found that 12% of those surveyed

had surges damaging their fire

pumps.

Below are the major NEC Sections requiring surge protection. On

page two is a selection chart for Bussmann series surge protective

devices (SPD)based upon application.

620.51(E) “Where any of the disconnecting means in 620.51 has

been designated as supplying an emergency system load, surge

protection shall be provided.”

Added in 2017, this section was

added to address emergency

system loads such as elevators,

escalators, moving sidewalks,

chairlifts and associated

700.8 “A listed SPD shall be installed in or on all emergency

systems switchboards and panelboards.”

Added in 2014, this requirement

helps ensure emergency electrical

systems continue powering vital,

life-safety loads in the event of

damaging surges.

equipment.

645.18 “Surge protection shall be provided for Critical

Operations Data Systems.”

708.20 “Surge protection devices shall be provided at all facility

voltage distribution levels.”

Added in 2017, Critical Operation

Data Systems is defined by the

NEC as “Information technology

equipment systems that require

continuous operation for public

safety, emergency management,

national security or business

continuity.”

Added in 2008, Critical Operation

Power Systems (COPS) are

power systems that can include

HVAC, fire alarms, security,

communications and signaling

for designated critical operations

areas. Surge protection helps

ensure these systems will operate

as intended in an emergency

situation.

670.6 “Industrial machinery with safety interlock circuits shall

have surge protection installed.”

Added in 2017, this section was

added to address the concern

with safety interlock failure on

machinery causing a safety

risk to operators who may not

be aware of disabled safety

mechanisms.

can be applied along with any notes that help in understanding the

context of the application.

Understanding the following points will help ensure that the correct

surge protective device is specified for the electrical system or

equipment.

The examples show circuit breakers as the most typical means of

making connections to the panel phases, although connection with

fusible switches and lug connections are permitted, provided the

terminals are rated for the 10 AWG conductors used by the BSPD,

BSPA and SurgePOD SPDs.

•ꢀ

Typical North American electrical systems include single-phase,

split-phase, Delta and Wye.

•ꢀ

Selecting the wrong SPD generally arises from misunderstanding

Note: UL does not require using overcurrent protective devices

such as circuit breakers or fused switches as the SPD’s thermal

disconnect technology will safely take the SPD offline in the event

of a failure. Use of these devices is for facilitating connection to the

panel buses and installation convenience.

the nominal system voltage, ground and neutral connections.

•ꢀ

General convention has it that a “ground” wire is not counted as

a wire in the system description (e.g., 3 wire, 4 wire, etc.), but it

is counted as a connection point if the selected SPD has a ground

wire.

Contact Bussmann Application Engineering for electrical systems not

covered in this section.

•ꢀ

Selection of a device voltage rating for Wye systems must be

based upon its nominal system voltage rating and not on the leg-

to-leg voltages in the Wye.

•ꢀ

Bonded N-G configurations do not require protection at the

service entrance transformer, but protection is suggested in

downstream bonded N-G systems if the length of conductor

making the bond is greater than 10 feet (3 m)*.

ULType 1, 2, 3 andType 4 component assembly,

and data signal surge protective devices

Installing UL Type 1 and Type 2 SPDs

Installation option A: using feed through lugs

While differences will arise in the installation of different SPD

models on various electrical systems and locations inside an

electrical system, the following are general procedures and

considerations to follow.

7. Determine if the lugs are rated for stranded 10 AWG conductors.

If lugs are not rated for this size conductor, DO NOT install the

SPD unit, or replace lugs with appropriately rated lugs before

proceeding, or install the unit using installation option B.

At the start of this section are diagrams indicating the connection

points for the Type 1 and Type 2 SPDs contained in this guide and

the electrical system to which they can be connected.

8. Route and trim the leads so they reach their connection points

with the least amount of length.

9. Strip the lead ends to lug manufacturer’s specifications, insert

them into the appropriate ports and torque to the specified value

NOTE: DO NOT install more than one lead into the same lug

port.

Installation steps

1. Inspect the electrical panelboard to be sure it is properly grounded

in accordance with prevailing code requirements.

2. Inspect the SPD unit to determine:

Go to step 13.

•ꢀ

It has the correct nominal system and MCOV voltage rating

and is the correct configuration for the installation.

Installation option B: circuit breaker or fused switch

When using a circuit breaker or fused switch, see suggested

ampacities in Table A for the SPD family product being installed.

•ꢀ

It is not damaged; If the unit is damaged or not correct for the

system, do not install it. Secure a proper replacement before

proceeding with the installation.

10. Place in the OFF position and install a new, dedicated common

trip circuit breaker or fusible switch with fuses sized by SPD

family and located as close as possible to where the SPD unit is

mounted.

3. Deenergize panelboard and follow established lockout / tagout

procedures. Remove panelboard cover(s) to gain access to the

interior. Check to make sure the entire panelboard is deenergized

before proceeding.

11. Route and trim the leads so they reach their intended connection

points with the least amount of length.

4. Select a location on the panelboard that accommodates mounting

the SPD and allows the leads to reach their intended connection

points. Be sure the SPD unit can be positioned so that the LED

status indicator(s) is visible. A location that permits the shortest

lead lengths is preferred.

12. Strip the lead end to fit the connection points, insert into the

terminal lugs and torque to the specified value.

Go to step 13.

Finishing the installation

13. Reinstall the panelboard cover(s).

5. Remove a 3/4” knockout or make a 1-1/16” diameter hole where

the SPD is to be mounted.

14. Test the SPD installation by energizing the panelboard and

placing the circuit breaker or fusible switch (requires fuses to be

installed) in the ON position. Verify the LED status indicators are

functioning according to the installed SPD model. If LEDs are

not properly displaying for a correctly installed and functioning

SPD (per model), see the troubleshooting procedures for

possible causes and remedy.

6. Remove the locknut from the unit and insert leads through the

panelboard wall being careful not to damage the conductor

insulation. (For NEMA 4X installations, use appropriate gaskets or

sealing means to retain the NEMA 4X rating on the installation —

see Figure 1.) Reinstall locknut and tighten to specified torque.

NEMA 4X installation requires appropriate

customer-supplied gasket between

the SPD and enclosure wall.

† SPD voltages are measured from Line-to-Neutral, or Line-to-Ground on systems where there is no neutral present. These units do not have a line-to-neutral, so the line-

to-ground voltage is 120 V for the 208 V Wye L-G and 277 V for the 480 V L-G, making the normal voltage applied to the unit less than the MCOV values listed in the

table.

Frequently asked questions (FAQs)

5. How does an SPD work?

1. Why are surge protective devices needed?

A surge protector works by momentarily “switching” from a high

impedance state into a highly conductive, low impedance state and

shunting the surge energy to the ground and in doing so, limits the

overvoltage to a lower, acceptable level. When the surge event is

over, the protector returns to its high impedance state, ready for the

next event or at end of life, fails open safely until replaced.

Electronic devices and equipment often contain microprocessors

that rely on fast digital ON/OFF coded sequence signals. Distortion

on power or signal lines may disrupt these sensitive signals. As

electronic equipment become smaller and more powerful, they

become more sensitive to power and signal line distortions —

particularly due their circuit density (microchips having literally

thousands of transistors on a single chip). To help safeguard

microprocessor reliability and uptime, surge protective devices have

become the standard technology so that they don’t get “upset,”

“degraded” or “damaged” by surge events, depending on the surge

magnitude, the system configuration and load sensitivity.

In other words, the SPD acts as a pressure relief valve. The pressure

relief valve (SPD) does nothing until an overpressure (voltage surge)

occurs in the supply (power) similar to the pressure relief valve.

6000V Voltage Surge

2. What are surges, transients and temporary overvoltages

(TOVs)?

700V Residual (Let-Through) Voltage

L

All these are various forms of voltage disturbances and they are

often used interchangeably. The true definition of these terms is

related to their defined duration.

SPD

Circuit

Load

Transients as defined by IEEE Standard 1313.1-1996 are “a short-

duration highly damped, oscillatory or non-oscillatory overvoltage,

having duration of a few milliseconds or less. Transient overvoltage is

classified as one of the following types: lightning, switching and very

fast front, short duration.” These can be generated by voltage spikes

which contain very little energy but are sufficient in voltage to cause

damage to sensitive electronics.

Current

Shunt

N/G

6. What is shunting?

Shunting is the term used to describe the process by which an

SPD redirects voltage transient energy to ground through a low

impedance path.

Surge is an overvoltage condition that usually lasts longer in

duration, >10 µs and <1 Ms and has higher energy to them that can

cause damage to electrical and electronic equipment.

7. How do I select and specify an SPD?

When it is determined an SPD is desired or required, specifying an

SPD involves:

Temporary Overvoltage (TOV) are created by faults on the utility

power distribution system and can cause extensive damage since

their time domain is much longer (ms to seconds to hours).

•ꢀ

Knowing the installation location and whether you can use Type 1,

Type 2 or Type 3

•ꢀ

Determining the system type (single-phase, split-phase, Wye or

Delta)

•ꢀ

Determining the system voltage

See page 5 for determining the location and suitable Type, and page

10 for specifying electrical system type and voltage.

Time

Once all three are known, you can start the specification process by

going to the appropriate product group:

•ꢀ

Type 1 UL Listed, NEMA 4X — SurgePOD PRO

3. What is a surge protector?

•ꢀ

Type 1 and Type 2 NEMA 1 and 4X — BSPD or BSPA

A surge protector is a device that limits transient overvoltages to

a safe level, thus protecting equipment it is connected to from

damage. A surge protector is generally referred to as an SPD (Surge

Protective Device). There are different variations of SPDs such as

lightning arresters and surge arresters or secondary surge arresters.

Open Type 1 UL Listed DIN-Rail — BSPMA black label high SCCR

Type 4 component assembly UL Recognized — Blue label low

8. Can anyone install an AC or DC SPD?

4. What is the difference between terms “Surge Arrester,”

“Surge Protective Device (SPD)” and “Transient Voltage

Surge Suppressor (TVSS)”?

All SPDs, whether AC or DC, should be installed by qualified

personnel following established safety procedures. This will help

ensure that all the safety requirements and all local codes are met.

The most common installation is in “parallel” to the load/device.

These terms are often used interchangeably and rather loosely.

However, the two terms have different meanings as determined by

the National Electrical Code^®(NEC) (www.nfpa.org), their UL listing,

and applicable IEEE/ANSI standards.

According to NEC Article 285 TVSSs have been redefined as “Surge

Protective Devices (SPDs) 1 kV or Less.” Previously titled “Transient

Voltage Surge Suppressors: TVSSs,” this Article now uses the

“type” designations that parallel the new requirements in UL 1449,

4^thEdition. It also includes general, installation, and connection

requirements for these SPD types installed on premises wiring

systems rated 1 kV or less.

9. What are the differences between series vs. parallel SPDs?

11. What technologies are used in making an SPD?

Series installed SPD are typically used at the equipment level, either

right in front of, or within the equipment they are protecting. These

SPD have an “input” and an “output” whereas parallel SPD do not.

A common example of a series connected SPD is a “surge strip.”

Since they are connected in series with the equipment, they conduct

load current. It is also common for a series AC SPD to contain a

EMI/RFI noise filter. This filtering is useful when it is right in front of

the equipment to filter out noise generated by other loads.

10. What is a DIN-Rail SPD with replaceable modules?

Compact

Replaceable module SPDs contain one or more field removable/

replaceable modules. The replaceable modules make maintenance

easy and minimize downtime. The modules are the heart of the

surge protector and usually contain the metal oxide varistors (MOV)

and thermal disconnect. In some instances external fusing is

required and or used in place of thermal disconnect.

The result is an arc voltage of about 20 Vdc. There are four stages of

operation before the tube fully switches.

Gas-Evolving

Insulating Material

Metal Oxide Varistor (MOV):

Electrode 1

An MOV is a variable resistor typically made of a large block of zinc

oxide grains. They act like semiconductors, an insulator below the

conduction voltage and a low value resistor above it. In conduction

mode, the MOV diverts and dissipates the transient. MOVs generally

connects in parallel to load. The thickness of the MOV determines

the clamping voltage and Diameter determines the current capacity.

1. Non-operating domain: Characterized by practically infinite

insulation resistance.

2. Glow domain: At the breakdown, the conductance increases

suddenly. If the current that’s drained off by the gas discharge

tube is less than about 0.5 A (rough value that differs from

component to component), the glow voltage across the

terminals will be in the 80-100 V range.

3. Arc regime: As the current increases, the gas discharge tube

shifts from glow voltage to the arc voltage (20 V). It is this

domain that the gas discharge tube is most effective because

the current discharge can reach several thousand amps without

the arc voltage across the terminals increasing.

13. Where is the best place to install an SPD?

15. What standards govern SPDs?

NORTH AMERICA — ANSI / UL 1449 4^thEdition

Ideally, an SPD should be installed at the main service entrance as

close to the neutral-to-ground bond as possible, as shown below.

This will ensure that surge energies are routed to earth by the most

direct path. In larger facilities where distances between this primary

protection and the equipment being protected are long, it is also

good practice to use distributed protection all the way to point-of-

use.

Low voltage surge protective devices – Part 1: Surge protective

devices connected to 50/60 Hz AC and DC power circuits, and

equipment rated up to 1000 V , or 1500 Vdc. The IEC standard is a

self certification or third party ^rc^me^srtification, such as KEMA, that will

test and validate the results.

14. What is distributed (cascaded) surge protection?

Distributed protection, cascaded protection or coordination is the

process of coordinating protection between the primary service

entrance of a large facility and the internal branch distribution panels.

Generally a surge protective device (SPD) with high surge handling

capacity is installed at the service entrance while SPDs of lower

surge ratings will be installed on the branch panels or dedicated

supplies feeding sensitive equipment. This approach can be taken

further to include point-of-use SPDs on long lines where they

terminate to sensitive or critical equipment. A further example of

such a distributed protection philosophy might include hard wired

SPDs at the main and sub-panels and additional plug-in protectors

on select equipment. (See pages 5 for SPD Types and installation

locations.)

17. What is UL 1449?

22. How long does an SPD last?

UL 1449 is the safety standard for AC surge protective devices

(SPD) used on systems with voltages of 600 Vac and less. This

standard addresses SPDs that are installed on the loadside of the

main disconnect. A UL 1449 Listed or Recognized surge protector

has been thoroughly tested for safe operations. A Voltage Protection

Rating (V_PR) is assigned to a UL 1449 Listed SPD as a result of these

tests to help users compare SPDs. UL 1449 4^thEdition went into

effect in September, 2009, making all previous 2^ndEdition SPDs

obsolete. Any older SPDs should be inspected and may be replaced

to meet the new safety standard prescribed by NEC Articles 280 and

285, which call for SPD Type products certified to the UL 1449 4^th

Edition.

How long an MOV-based SPD lasts depends upon how often it

experiences a surge and for how long. Every time an MOV becomes

conductive to shunt the surge to ground, its life is slightly degraded.

The greater the surge, the greater the degradation of the MOV. One

hit of 20 kA may degrade the MOVs life just as much as 15 hits

at 0.2 kA. So, based upon the size and duration of surges an SPD

encounters, it may last a day suppressing a large surge, or years

suppressing smaller surges.
