The electrical testing experts at Applied Technical Services perform DC Hipot testing of medium voltage cables to verify the safety and integrity of electrical cable insulation.

Hipot testing cables is a cost-effective method for ensuring the integrity and safety of insulation in electrical cables and systems. Our technicians start by preparing the test subject and setting up testing equipment before beginning the Hipot testing. This involves applying gradually increasing DC voltage between the conductors and the cable’s metallic shield or ground. Stressing the cable insulation allows our experts to identify any flaws or defects that could compromise performance, decrease safety, or lead to equipment failures during operation. Leakage current, insulation resistance, and any standard-determined or client specified conditions are monitored throughout the testing process to assess cable condition. ATS is ISO/IEC 17025 accredited in electrical testing and complies with our ISO 9001:2015-registered quality management system — adherence to industry standards and safety protocols helps to prevent damage to the cables and ensure the reliability of test results. The final results of DC Hipot testing of medium voltage cables determine whether the tested cable meets quality standards and is suitable for use in medium voltage applications. Our comprehensive reporting provides clients with detailed information on every step of the test, including testing conditions, as-found and as-left conditions, and any recommended actions.
