FQ-RCTA03 3000A Flexible Rogowski coil AC current transformer CT

flexible current transformer

The FQ-RCTA03 Flexible AC current probe 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.
