Insulation resistance test steps
NettetPerform an insulation-resistance test on each conductor with respect to ground and adjacent conductors. Test period must be for 1 minute using a voltage according to manufacturer’s published data. If no literature from the manufacturer is available, apply 500 volts dc for 300-volt rated cable and 1000 volts dc for 600-volt rated cable. Nettet10. sep. 2024 · Provided that the voltage quality is high with regard to low ripple, it can also be used to measure the insulation resistance in MΩ or GΩ. In this case, however, SCHLEICH also consistently refers to the test as insulation resistance test. For the HV-DC, the basis of the evaluation is the flowing current. This corresponds to the same ...
