Solid Rogowski Coil

The Magnelab solid Rogowski coil current sensors measure AC current up to a peak of 15,000 amps. Basically, the rugged, epoxy encapsulated construction makes the sensor ideal for switch-gear applications in harsh environments, such as switching equipment used in the transmission of electricity. This part is constructed to IEEE C57.13 insulation standards.
