Currently, the methods used for insulation monitoring in the energy storage field are mainly external resistance method and AC injection method. The AC current injection method generates a square wave signal which is then injected into the RC circuit between the HV line and the Protective Earth (PE) through an RC filter or transformer.
The insulation resistance value needs to be calculated twice. For each measurement, a known resistance is inserted between the positive and negative terminals of the battery and the grounding, and the voltage on this resistor is measured. This isolation measurement can be carried out regularly.
