Short-Circuit Testing TRIZ Cases
- Galvanic Isolation Testing Device Using AC Signals
A testing device applies an AC signal to phase lines and rectifies the response to verify electric connectivity across galvanic barriers.
- Ground Fault Detection Single Power Supply Accuracy
A ground fault detecting device uses a single power supply for signal generation and processing units to minimize detection errors.
- Communication Network Ground Fault Detection Circuit Breakers
Circuit protection devices share current data via a communication network to enable coordinated ground fault detection.
- Battery State Estimation via External Short Electromagnetic Field Analysis
An external short generator creates a known resistance signal that a sensor analyzes to determine internal resistance, avoiding complex AC equipment costs.
- Ground Loss Detection Circuit for Vehicle Safety Systems
A ground loss detection circuit monitors redundant ECU ground lines using shunt components to identify faulty connections.
- High-Voltage Cable Sheath Circular Current Monitoring System
Mobile vehicle with lifting assembly and protection mechanism detects circular current in high-voltage cable metal sheaths while preventing debris entry.
- Passive Bridge Circuit Leakage Surge Structure
A passive bridge circuit uses a leakage surge structure to draw current from a common node for monitoring.
- Ground Fault Detector Threshold Adaptation
A ground fault detector adjusts detection thresholds based on common mode capacitor capacitance for accurate anomaly identification.
- XMR Sensor Ground Current Monitoring for Motor Vehicle Control Units
An XMR sensor monitors ground currents in motor vehicle control units using magnetoresistive elements, eliminating bulky comparators to reduce device area.
