Fault Location By Conductor Types TRIZ Cases
- Fault Location in Two-Terminal Power Lines Using Single-Ended Voltage
A fault location method uses synchronized currents from both terminals and voltage from one terminal to determine distance.
- Fault Wave Arrival Determination Using Voltage Derivative
A power quantity scaling unit measures the derivative of line voltage to detect fault wave starting points in transmission systems.
- Fault Location in Branched Power Systems Using Reactance
Calculating sequence reactance without positive-sequence current measurements locates faults on branched, non-homogeneous power delivery systems.
- Magnetic Field Sensor Fault Detection for Overhead Power Lines
Magnetic field sensors analyze current changes via duration tests to eliminate false triggers from lightning surges and reduce fault location time.
