ISQ20 Commissioning Insulation Test We use power supply filters in our units to meet European EMC regulations. These filters have a discharge resistance to earth in each phase which is illustrated below. The resistance value is 1 M in each case. This results in an effective resistance of 333 k for a cumulative insulation resistance measurement (L1-L2-L3 to earth).
