| High Voltage Motor Diagnostics Monitor |
Introduction
HV motor insulation monitoring system -
:Stator winding insulation diagnostics
It is an on-line insulation condition monitoring system for high-voltage motors.
It measures and analyzes the partial discharges generated from the defects in the stator winding. Through monitoring, it can ascertain the relative condition of insulation, the deterioration of which is the leading cause of electrical failures.
Features
1. Insulation condition Stator winding
- Measures and analyzes the partial discharge generated from the
defects in the stator winding insulation
2. Temperature & Humidity
- Measures the temperature and humidity of the stator
