[vc_row][vc_column][vc_column_text]A Rogowski coil is an electrical device for measuring alternating current (AC) or high-speed current pulses. It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The whole assembly is then wrapped around the straight conductor whose current is to be measured. There is no metal (iron) core. The winding density, the diameter of the coil and the rigidity of the winding are critical for preserving immunity to external fields and low sensitivity to the positioning of the measured conductor.
Rogowski loops are simple and reliable inductive sensors that measure the net current through the cross-section of the loop. They can be highly accurate and insensitive to currents in nearby conductors provided they are sufficiently uniform. There are many successful applications inscience and industry.

安装说明 Installation specitication
1 Before the installation must ensure that the primary is no current status
2 Correct mouting of the CT is assured by a distinct sound of a click~
3 When Install CTs into circuit box, the circuit box’s main breaker should be turned off to perform.
