The Corona Probe is an off-line instrument to accurately pinpoint the source of partial discharge (PD) in a particular slot in generators and motors. Complete kit comes with PPM-97 peak pulse meter, ferrite probe, ground strap and handy carrying/storage case.
The Corona Probe (originally known as the TVA probe) is used to locate partial discharge in each slot with the winding energized phase by phase. It supplements on-line partial discharge monitoring. The PPM-97 probe is generally used on motors and generators with rated voltage greater than 6 KV.
