ROG4K 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 Description included in the EM210 analyzer, thus neither additional wiring nor space are required the sensor is directly Current sensor based on the Rogowski principle, connected to the analyzer. Fast installation. The opening/closing mechanism to be used in combination with the EM210 analyzer makes installation fast even in existent applications. The (versions EM210 72D MV5 and EM210 72D MV6) analyzer only requires two cables to be connected per to measure current in single-phase, two-phase sensor and the installation is made easy by the color and three-phase systems. (black, orange, blue) on the connection cable. 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 02/05/2018 ROG4K DS ENG Carlo Gavazzi Controls S.p.A. 1ROG4K Structure C A D B Area Description A Analyzer connection cable B Coil opening/closing mechanism C Colored sensor identification D Coil 02/05/2018 ROG4K DS ENG Carlo Gavazzi Controls S.p.A. 2
