Document Type and Number:
WIPO Patent Application WO/2022/025338
Kind Code:
A1
Abstract:
An insulation monitoring device, according to various embodiment of the present application, comprising an impedance formed between a power line and a ground of a system comprises, a signal generation circuit for applying a triangular wave signal to the power line through a signal measurement circuit, the signal measurement circuit for measuring a voltage difference across the detection resistor of the signal measurement circuit or a current flowing through the detection resistor when the triangular wave signal is applied to the impedance, a control circuit for obtaining an impedance value of the impedance based on at least one of the voltage difference and the current, and monitoring the impedance value.
