The Choice of 10 kV Neutral Point Operation Mode in Fushun Grid

Abstract:

This paper discusses that the capacitive current is a must of producing arc grounding overvoltage, and the method and necessary to restrain arc grounding over voltage. It also explains the concept of capacitive current and arc suppression coil, and the test method and significance of measuring capacitive current. Based on the comprehensive field test and evaluation of 29 substations, it provides the correct selection of neutral point operation mode and gives a development direction to 10 kV power network neutral point grounding method of Fushun grid.
