Study on Measure to the Reduction of the Surge Voltage on Low Voltage Circuit in Substation

Abstract

In order to improve the reliability of electric power systems, it is important to reduce the malfunction of relay or the fault of low voltage control circuits in substation by switching and lightning surge. However, it is not enough that the study of intrusion of surge into the low voltage control circuits. We studied the terminal voltage of the control panel and analyzed the intrusion route of surge in substation.
