Abstract:

A method of non-grounded neutral point is widely used in the power system of coal mine, Insulating parameter is decided to mine the important parameters of the power supply security conditions. The state grid insulation measurement, be helpful for the timely discovery security hidden danger, and it’s important to improve the security of performance and reliability of power system’ s supply. based on the existing insulating parameter based on the method of measuring, The paper puts forward the method of measuring insulation into improve signal parameters, this method has good safety, simple operation, high precision measurement features
