ABSTRACT:
A method for measuring and supervising an insulation resistance and stray capacitance against ground of a power supply line while the line is active condition. A frequency different from the main supply voltage is applied to the line and this voltage is detected by a coupling transformer and the insulation resistance and the stray capacitance can be obtained by operation work of the measured value.
