Emergency Protection Detection TRIZ Cases
- Electric Leakage Protection Device with Self Leakage Generator
A self leakage generator uses parallel short circuits with selectable resistance components to produce consistent detection current.
- Fault Location Detection Using Fourier Derivative Analysis
A fault location detection apparatus calculates current derivatives via Fourier transformation to determine precise distance along power transmission lines.
- Multi-stage Fuse Protection for Electrical Loads
Segmented fuse circuits lower downstream component ratings while maintaining overvoltage protection via voltage terminal short-circuiting.
- Reactance-Injecting Module Fast Fault Neutralization
Dedicated communication links enable the reactance-injecting module to bypass impedance within one millisecond, preserving fault localization accuracy.
- MOSFET Regulator Rectifier Protection Against Reverse Voltage
Dynamic switching isolates regulator rectifiers from reverse voltage and short circuits without continuous power loss.
- Earth Fault Direction Detection Using Zero Sequence Energy
Calculating zero sequence active and reactive energy stabilizes directional detection during intermittent faults in compensated networks.
