Circuit Interrupters Testing TRIZ Cases
- Relay Contactor Movement Detection for Faulty Coil State Diagnosis
Comparator-based coil voltage and current checks detect unintended relay contactor movement and flag faults before shocks or malfunctions create hazards.
- Relay Contactor Movement Detection Using Dynamic Coil Current Thresholds
Dynamic coil-current threshold tracking detects abnormal relay contactor movement and flags faults before safety-critical failures.
- Relay Coil Current Detection for Contactor Movement Faults
Dynamic threshold tracking of relay coil current detects Back-EMF anomalies, contact bounce, and faulty contactor movement early.
