Short-Circuit Testing TRIZ Cases
- Blender Ground Fault Detection Circuit for Homes Without GFCI Outlets
See how an integrated ground fault detection circuit uses ground planes to prevent electrical s
- Leakage Interruption Circuit for Low-Power AC/DC Fault Detection
A current-limited leakage interruption circuit cuts standby power while detecting AC and pulsating DC faults and supporting self-test.
- An electronic circuit breaker with self-triggering protection for a vehicle, and a method therefor
Voltage-based self-triggering protection turns a MOSFET vehicle breaker off during over-current and short-circuit faults without shunts or external triggers.
- Dynamic MHO Distance Relay Control Against Overreaching
Controls dynamic MHO expansion in distance relays with a user-set limit to prevent overreaching and improve fault identification.
- Inverter Ground Fault Detection Using an Earthing Transformer
Phase-voltage comparison with an earthing transformer detects floating-neutral ground faults and isolates the inverter before damage occurs.
- Vehicle Power Network Disconnect Control for Fault Isolation
A regulated disconnect keeps energy flowing across vehicle sub-networks during faults, enabling fast fuse tripping and protecting fault-free loads.
- HVAC Ground Fault Interruption for High Leakage Current Loads
Dual ground fault sensing separates branch faults from normal HVAC leakage, preventing nuisance trips while maintaining shock protection.
