Product Description

The Iris Power Corona ProbeTM Model PPM-97 is a portable, battery operated instrument for off-line detection of partial discharge in rotating machinery. The instrument, with its ferrite probe, is designed to measure partial discharge pulses. The corona probe test is a valuable aid for detecting the presence of abnormal partial discharges in stator winding insulation. It is one of the best tools for pinpointing the exact location of PD activity within the core sections of a stator winding.

The Iris Power PPM-97 Corona Probe supplements on-line PD measurements by more precisely locating the PD to a particular slot and position, with the winding energized phase-by-phase using a high voltage AC source. Alternatively, it can be used as a stand-alone PD test for locating activity in the winding where no other PD information is available. The Iris Power Corona Probe can also be used to check the quality of bonding between groundwall 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.
