Insulation Resistance Tester
Helps assess insulation affected by moisture, contamination or ageing. Temperature and previous readings matter more than a single isolated result.
Measurement method
The isolated equipment is tested at an appropriate voltage. Duration and environmental conditions are recorded, and safe discharge is confirmed before disconnecting.
Field applications
- Winding-to-earth insulation assessment
- Before-and-after maintenance comparison
- Trend monitoring for MV/HV assets
