Flexible Rogowski coil
RosCoils uses open-loop structure, can be used to measure the large size (conductor dimension≥3m), out-of-shape or narrow conductor current (especially when traditional forcipate current probe can’ t measure the current, flexible rogowski coil current sensor can do it conveniently). Lead wire which passed through by tested current can across coil without cut. It can sense the current in rogowski coil, and measure the current in tested wire.
