DC Hipot Testers

DC hipot testers apply a controlled, high‑voltage DC potential to electrical equipment to verify insulation strength and other electrical performance factors under stress. They measure leakage current and insulation performance to detect degradation early, supporting preventive maintenance programs and troubleshooting of insulation failures before they result in unplanned outages or safety incidents.

DC hipot testing generally evaluates high‑voltage cables, large motors, and DC power systems, while AC hipot testing is typically required for grid‑connected equipment. Many modern power systems incorporate both AC and DC elements, making both test methods necessary for complete verification.

ATEC carries DC hipot testers from industry‑leading manufacturers, including High Voltage Inc., Hipotronics, HV Diagnostics, and Phenix Technologies, offering a wide range of portable and high‑capacity systems to meet utility, industrial, and power‑generation testing requirements.
