Flexible Rogowski Coil 1000A/100mV

Flexible Rogowski Coil 1000A/100mV

Jiangyin Spark FCT rogowski coil is flexible, like rope ,it is designed to use where solid or split core current transformers cannot fit Advantage including high accuracy, wide measurement and frequency range and very light weight.The probes comprise a flexible air–cored sensor which can be opened, allowing them to be installed around a primary conductor without interrupting the circuit. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas and with large conductors.
