Analysis of Measurement and Calculation for Coal Mine High Voltage Grid Grounding Capacitance Current
Abstract：Single-phase grounding fault makes a grate influence on the coal mine high-voltage power security of power supply. With the rapid development of coal mine cable network, grounding capacitance current is increasing gradually. So it is necessary to measure and calculate the grounding capacitance current of power network correctly and conveniently. The practical calculation method of coal mine high voltage power grounding capacitance current is described, by which the calculation for coal mine single-phase grounding capacitance current is carried out. Compared with the measured value, the calculation result is reliable.
