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.
One sensor per phase in the motor terminal box.
One sensor per phase in the motor terminal box.
All types of sensors are compatible for use with the HVPD Kronos® Permanent and HVPD Kronos® Spot Tester.
