IEC 60840 / 62067 Test Voltage Calculator
Compute U0, the AC withstand test voltage (1.7 U0), the PD test voltage (1.5 U0), and PDIV investigation threshold for a given cable rated voltage. Use as a sanity check against your cable's type-test specification.

Calculated values follow IEC 60840 §15.4 / §16.3 and IEC 62067 for EHV. Routine and commissioning ratios may differ from utility-specific procedures; verify against your test specification. PD acceptance limits depend on cable construction, asset criticality, and utility practice — the 5 pC figure is a widely cited typical value, not a hard universal limit.
