WebThese standard minimum insulation resistance (IR) values (for single conductor cable) are based on the following formula: IR = K log 10 (D/d) Where, IR is in meg-ohms per 1000 ft of cable, K is a constant for insulating material, D is the outside diameter of conductor insulation and d is the inside diameter of conductor. Web2 mei 2024 · DC hipot testing measures the insulation resistance of cables by applying high voltage and measuring leakage current, and the resistance is calculated using Ohm's law. The test voltage values for DC hi-pot tests are based upon final factory test voltage, which is determined by the type and thickness of insulation, the size of conductors, the … towerview church bangor
