EM210 energy analyzer current sensor (20-4000 A)

Beneﬁts

• Adaptability and ﬂexibility. Eﬀective for a wide range

of currents and available in three diﬀerent lengths, it can

be installed in existent applications and/or with reduced

space, on single cables, on cable bundles or high

capacity busbars.

• Accuracy. The lack of a ferromagnetic core improves

measurement accuracy in a wide range of currents and

eliminates possible interferences.

• Simpliﬁed system. The current calculation integrator is

included in the EM210 analyzer, thus neither additional

wiring nor space are required; the sensor is directly

connected to the analyzer.

• Fast installation. The opening/closing mechanism

makes installation fast even in existent applications. The

analyzer only requires two cables to be connected per

sensor and the installation is made easy by the color

(black, orange, blue) on the connection cable.

Description

Current sensor based on the Rogowski principle,

to be used in combination with the EM210 analyzer

(versions EM210 72D MV5 and EM210 72D MV6)

to measure current in single-phase, two-phase

and three-phase systems.

Compact, ﬂexible and lightweight, it is suited to

all applications and can be installed in all types of

switchboards.

Supplied in a kit made up of three diﬀerent colored

pieces to make phase identiﬁcation easy, it comes

with coils with three diﬀerent diameters and lengths

and measures a wide current interval (from 20 to

4000 A).

Operating principle

The Rogowski sensor is an alternating current measurement device.

Unlike current sensors with ferromagnetic core, the linearity of the Rogowski sensor makes it speciﬁcally

indicated to measure high currents.

Its operating principle is very simple: a voltage signal dependent on the primary current trend, which can be

reconstructed using an integration process, is generated at the ends of the coil positioned around a conductor.

Unlike traditional Rogowski sensors, ROG4K does not require an external integrator with additional power

supply since measurement is entirely controlled by the analyzer.

Applications

Indicated for retail and industrial solutions, especially for retroﬁtting and/or contexts with reduced available

space where installing a current sensor with ferromagnetic core is diﬃcult.

It is especially indicated to measure:

• industrial or building system load

• single machine load with high current absorption
