The FQ-RCTA02 3000A FLEXIBLE ROGOWSKI COIL AC CURRENT SENSOR FOR POWER QUALITY ANALYZER is designed for easy installed in tight spaces and without the need for dismantling the primary busbar or cables. It includes a flexible Rogowski coil probe and electronic modules. The signal from the coil probe can be amplified by the electronic modules through the integration processing. The output signal can be directly used in oscilloscope, digital multimeter or data logger recording instrument.
Rogowski coils allow for installation over various conductor sizes or grouped cables. The coil output gives a low voltage signal; therefore there is no danger from an open-circuited secondary.
A Rogowski coil current sensor is an electrical device for measuring alternating current 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.
