Fault Location By Conductor Types TRIZ Cases
- Wye-Grounded Utility Fault Location Using Relay History Analysis
Relay records, oscillography, and short-circuit studies pinpoint transient and complex utility faults for faster field response.
- Transmission Line Fault Location Using Delta-Sigma Wave Sampling
Delta-Sigma sampling and filtering capture traveling-wave arrival times for accurate transmission line fault location with lower processing demand.
- Submarine Cable Fault Pinpointing With HV Pulse Reflection
High-voltage pulse discharge and reflection analysis pinpoint faults on long submarine power cables despite noise, reducing un-trenching and repair time.
- Traveling-Wave Fault Location for Complex Branch Power Lines
Arrival moments from distributed traveling-wave sensors resolve branch and trunk faults in complex power lines with fast, reliable locating.
- Power Grid Planning Evaluation With Hybrid Weighting and Regression
Hybrid weighting, similarity assessment, and nonparametric regression reduce bias in power grid planning evaluation and improve accuracy.
- Power Network Fault Location Using Phase Angle Areas
Synchronized voltage and current phase-angle analysis locates power network faults by area while reducing measurement units and system cost.
- Pole-Mounted Sensor Fusion for Real-Time Power Line Anomaly Detection
Multi-sensor pole monitoring combines imaging, sound, Lidar, infrared, radar, and weather data to predict power line anomalies in real time.
- Fault Pulse Catching for Power Distribution Circuit Discrimination
By combining current peaks, pulse duration, pulse intervals, inverse pulses, and voltage loss, this case improves faulted circuit discrimination.
