Automated Digital Hipot Testers for Electrical Safety Testing

A hipot tester (also called a dielectric withstand tester) applies a high potential between isolated conductive parts to verify insulation integrity and confirm that a product can withstand the specified test voltage without breakdown or unacceptable leakage. In practice, hipot testing is widely used in product safety laboratories, manufacturing quality control, and compliance testing programs.

ED&D’s Millennium Series automated digital hipot testers are designed to simplify routine high-voltage testing with 1-button operation, visible and audible pass/fail indication, and a safety protected start switch. Both models also support low current ground continuity testing as part of the electrical safety test workflow.

In practice, these testers are suited for routine dielectric withstand verification in bench-top compliance testing, incoming product evaluation, production-line test stations, and audit-ready laboratory programs where repeatability, documentation, and operator efficiency matter.

Hipot testing is commonly used to verify dielectric withstand requirements associated with standards such as IEC 60335, IEC 60601, IEC 60950, IEC 61010, and related product safety requirements including UL 1703. For thin insulation accessory testing, related applications may also reference IEC 60065 and UL 6500.

Technical note for EMC-filtered products: when testing products that incorporate EMI filters, an AC hipot test may cause the Y capacitors in the filter to conduct current, which can create false failures or stress those components. In many such cases, an AC/DC hipot tester is the more appropriate choice.

The ED&D HP-2000 is an automated AC/DC digital hipot tester intended for electrical safety laboratories and production environments that require both AC dielectric withstand testing and DC hipot capability. It is particularly useful for products where circuit design features such as EMI filters make DC testing the more appropriate method.

Product Details

  • 1 button testing — no setup required, just plug right in
  • Easy to identify PASS / visible and audible FAIL indication
  • Auto test time: 1 sec. / 60 sec. +
  • Safety protected start switch
  • Supports low current ground continuity testing as part of the electrical safety test workflow
  • Used for dielectric withstand testing associated with UL, CSA, IEC, EN, and other electrical safety standards
  • Includes ISO/IEC 17025 accredited calibration certificate, accredited by ACLASS

Why choose AC/DC? When hipot testing products that incorporate EMI filters for EMC regulations, AC testing can cause the Y capacitors in the filter to conduct current, creating false failure indications and possibly damaging those capacitors. Many standards permit DC testing at 1.414 times the AC test voltage, which is why an AC/DC hipot tester is often the correct solution.

Frequently Asked Questions

What does a hipot tester do?

A hipot tester applies a high voltage between isolated conductive parts to verify insulation integrity and confirm dielectric withstand capability without electrical breakdown.

What is the difference between the HP-1000 and HP-2000?

The HP-1000 is an automated AC digital hipot tester, while the HP-2000 is an AC/DC digital hipot tester that adds DC test capability for applications where AC-only testing is not ideal.

When should a lab use DC hipot testing instead of AC?

DC hipot testing is often preferred when testing products that incorporate EMI filters, because AC testing can cause Y capacitors to conduct current, resulting in false failures or unnecessary component stress.

Do these hipot testers include calibration documentation?

Yes. Both models include an ISO/IEC 17025 accredited calibration certificate, supporting traceability for regulated test lab and audit environments.

Can the HPA-01 be used for testing thin insulating materials?

Yes. The HPA-01 accessory device is intended for dielectric voltage withstand testing of thin insulating materials such as transformer insulation and circuit board insulation when used with a compatible hipot tester.
