Smart current sensors
17 June 2016
Offering innovative and high quality solutions for measuring electrical parameters in Smart Grids, Industry 4.0 and renewable energy market, LEM has introduced a new LEM City range of products for future Smart Cities.
LEM has developed the “ART” Rogowski current sensor to measure current of up to 10000A AC and beyond. The ART achieves IEC 61869 Class 1 accuracy without the need for additional components like resistors or potentiometers, which can drift over time.
In addition, the ART benefits from “Perfect Loop” technology, a unique patented coil clasp that eliminates the inaccuracy caused by sensitivity to the position of the conductor inside the loop as well as providing an innovative, robust and fast “Twist and Click” closure.
