  • Testing and Commissioning Requirements for Switchgear

    Insulation resistance measurement is based on Ohm’s Law. By injecting a known DC voltage lower than the voltage for dielectric testing and then measuring the current flowing, it is very simple to determine the value of the resistance. In principle, the value of the insulation resistance is very high but not infinite, so by measuring the
