For accurate DC hipot test readings, it is necessary to follow proper procedures for safety and reliable test results.
Because DC hipot testing utilizes high voltage of more than 5 kV, techs must watch for the leakage current levels in order to measure how much current is running through the cables. The cable capacitance will indicate a sudden rising in current if insulation is faulty so the proper cable test equipment is needed to ensure that measurements are accurate. Without the proper equipment, results are not assured and the end result could be a safety issue for those around the electrical system or even unit failure because of damaged or faulty insulators.
You can minimize the risk of injury and obtain better readings by making sure that all objects in the immediate area of the equipment being tested are properly grounded. There should be enough clearance around testing equipment and terminals so no flash overs will occur. Additionally, keeping terminals clean, moisture and contaminant free will provide better testing results, and a continuously clean power supply running through the power line will offer the most reliable testing without any fluctuation errors.
Hipot testing should always be performed in cool and dry weather because moisture and humidity increase the chances of higher leakage current and poor measurement results.
