Study on Influence of Divided Conductor with Mechanical Properties on Operating over Voltage in Power System

Article Preview

Abstract:

This paper analyzed the influence that divided conductor to electrical fast transient burst. Divided conductor may change the magnetic field distribution around the conductor, but accordingly increased conductors electrical susceptance. The mechanism that the disconnecting switch cut off the power line when the no-load current is at peak and electric arc distinguished when the current pass zero and accordingly restraining measure is proposed. The outcome showed that the model can simulate the electrical fast transient burst in capacitive power line and makes it easy to analysis complex power system problems based on simple model. The method is proved to be correct and enforceable by validation of protective measures.
