WebJul 24, 2024 · The IR test procedure has four phases namely charge, dwell, measure, and discharge. First phase – Charge In the first phase, you should increase the voltage from zero to the preferred voltage of your equipment, so that it provides the stabilization time and limits the inrush current to the DUT. Second phase – Dwell WebThe testing of insulation resistance in a cable is done to determine the resistance value to the current flow across it. If there is a high resistance then it means a very low current is …
