A Highly Efficient Detection System of Leakage Currents of Grounding Faults
This work explored the realization of a detection algorithm and system for leakage currents of transmission lines grounding faults.The system employed the technique of pulse width modulated DC power supply to imitate the scene of transmission.The fault features and data status were analysed and determined intelligently so that the process standard and the lookup speed of transmission fault could be increased.Meanwhile the mathematic model was created to deal with the transmission fault quickly and effectively with the worker.The use of the system achieved an average time of fault di-agnosis of 4 hours from 2020 to 2022 and a first-attempt success rate of 69%.
