Short-Circuit Testing TRIZ Cases
- Impedance-Based Ground Disconnect Detection Across Isolated Voltage Domains
Capacitive coupling and impedance monitoring detect degraded or disconnected grounds across isolated 12V and 48V domains before faults spread.
- Battery Short-Circuit Detection Using Voltage-Step Current Response
A slight voltage drop reveals current-response differences that detect battery internal short circuits more accurately and support earlier warnings.
- Adjustable Earthing Access Housing for Cast-In Concrete Testing
An adjustable cast-in housing brings earthing connections to the finished concrete surface for non-invasive testing and fault checks.
- Three-Phase Inverter Short-Circuit Detection Without Full Shutdown
Phase-current change matching detects inverter phase-to-phase shorts early, enabling selective switch blocking to prevent damage and keep drive function.
- UPS Ground Fault Detection Using Filter Circuit Voltage Sensing
Filter-circuit voltage sensing locates ground faults in three-phase UPS units while avoiding extra hardware, false trips, and added heat.
- Relay Output Bias Monitoring for Short-to-Ground Protection
A bias voltage check at the relay output detects short-to-ground faults before closure, preventing relay and load damage.
- UFS Memory Voltage Path Detection for Cross-Version Compatibility
Driving voltage path detection identifies the UFS memory version early, enabling correct voltage selection without added PCB complexity or side effects.
