Winding Resistance Tester
Differences between phases or tap positions can reveal possible loose connections, contact defects or winding anomalies.
Measurement method
After suitable connections are made, readings are taken once current stabilizes. Each phase and tap is recorded with temperature, and leads remain connected until discharge completes.
Field applications
- Phase-to-phase winding comparison
- Tap-changer contact investigation
- Post-repair resistance verification
