High Voltage Coupling Capacitor (HVCC)

Measure Partial Discharge (PD) activity in the stator windings of motors and generators

Our HVCC Sensors Are Designed for Permanent Installation on MV/HV Rotating Machines to Measure PD Activity in the Stator Windings

The HVCC sensors measures PD pulses occurring in the machine’s stator winding through a direct galvanic connection to the HV terminals. Designed for permanent installation, with the signal connections brought out to an external termination box, the sensor enables on-line PD monitoring and spot testing without the need for an outage. One coupling capacitor is installed on each phase of the machine for measurement of both phase-to-phase (end-winding) and phase-to-earth (slot section) discharges.
