High Voltage Coupling Capacitor (HVCC)

High Voltage Coupling Capacitor (HVCC) sensors are designed for permanent installation on MV/HV rotating machines to measure PD pulses occurring in the stator windings via a direct galvanic connection to the HV terminals.

Once permanently installed, 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.

All types of these sensors are compatible for use with the HVPD Kronos Permanent and HVPD Kronos Spot Tester.
