Iris - Model PPM-97 -Corona Probe for Precise Partial Discharge Monitoring

The Iris Power PPM-97 Corona Probe supplements on-line partial discharge measurements by more precisely locating the partial discharge to a particular slot and position, with the motor or generator winding energized by an external high voltage AC source. This offline test provides a method of testing the quality of bonding between the ground wall insulation layers in the slot sections of new resin-rich and individually VPI’d coils/bars, and the adequacy of slot resin fill in global VPI windings.
