Transformers Testing TRIZ Cases
- Current Transformer Secondary Open-Circuit Fault Detection
Dynamic time-window selection from secondary current changes improves open-circuit detection and avoids false breaker trips.
- Current Transformer Secondary Circuit Interruption Detection
Mean current and change-threshold analysis detects secondary circuit interruptions in current transformers and avoids false breaker trips.
- CVT Voltage Divider Dissipation Factor Measurement Without Disassembly
GST and UST current measurements let engineers assess CVT voltage divider insulation and faults in situ without disassembly.
- Transformer Partial Discharge Sensing With UHF Position Localization
Combining omni-directional and directional UHF sensing with light detection locates transformer partial discharge without shutdown or oil draining.
