Voltage Withstand Test (Hi-pot)

The Voltage Withstand Test, commonly known as the Hi-pot Test, verifies the insulation strength of electrical cables and components by applying a high voltage for a specified time. This test ensures that the system can operate safely under peak voltage conditions, without breakdown, leakage, or insulation failure — essential for commissioning, preventive maintenance, and quality assurance.

High Voltage Insulation Testing

Applies AC or DC high voltage to detect insulation weaknesses or manufacturing defects.

Suitable for LV, MV, and HV Systems

Test conducted on cables, switchgear, bus ducts, and electrical panels across all voltage classes.

Preventive & Pre-Commissioning Tool

Ensures insulation health before energizing systems, reducing risk of future faults or hazards.

Certified Testing & Detailed Reporting

Compliant with IEC/IS/IEEE standards and includes a comprehensive test report with pass/fail results.

End-to-End Hi-pot Testing Process

High Voltage Testing for Insulation Integrity & Safety

Preparation & Isolation

Disconnect and isolate test objects; ensure safe conditions and grounding as per protocols.

Step 01

Voltage Application

Apply high test voltage gradually using calibrated Hi-pot equipment (AC or DC based on test standard).

Step 02

Monitoring & Fault Detection

Monitor for insulation breakdown, arcing, or leakage during the test period.

Step 03

Report Generation & Certification

Generate certified test reports with voltage levels, duration, leakage current values, and safety recommendations.
