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
