Item no. 855-9300/500-000

Rogowski coil; Primary rated current: 500 A; Output signal: 10.05 mV; Cable length: 3 m


Short description:

The Rogowski coil is a closed-air coil with non-magnetic split core, placed around a conductor or a current bar.

The magnetic field produced by the AC current flowing through the conductor induces an output voltage in the coil.

This measurement procedure provides galvanic isolation between the primary circuit (power) and secondary circuit (measurement).

Easy placement of the Rogowski coils allows existing systems to be retrofitted without time-consuming installation or process interruption.

The Rogowski coil can be used together with the 789-652 Signal Conditioner or the 857-552 Rogowski Signal Conditioner.

  • Split-core style coil for easy installation
  • Ø 55 mm coil aperture for non-contact measurement
  • 1.5 m or 3 m output cable
  • Insulated plastic case to UL 94-V0
