Withstand voltage
Updated 2026-10-27
Data records
- Withstand voltage is a specified test voltage, above the normal operating voltage, that insulation is required to sustain for a set time without breakdown or excessive leakage current. A withstand test is a pass or fail proof test rather than a measurement of insulation quality.
- In very low frequency test set practice a withstand test is configured as a single step at the required test voltage held for the required time, and the set can be taken directly to that voltage rather than stepped up through intermediate levels.
