Introduction
This is to measure PD(Partial Discharge) signals generating at stator winding while high-voltage motor or generator is operating and to diagnose the deterioration state of motor or generator.

Features
1. Wide evaluation for frequency band is available.
2. Ceramic Coupler that intercepts high-voltage power and couples PD signals only

 Applications
1. Sense deterioration of stator winding in a high-voltage motor
2. Insulating deterioration evaluation of high-voltage insulating materials
?(Sense RF signal components that appear upon insulating deterioration.)
