This arc voltage calculator can help you understand how a Dielectric Withstand Test helps your quality process. This calculator also shows how using a Helium atmosphere can help your test be more stringent. If you have any questions about high voltage testing or this calculator please call us - 1-800-441-9910.

| Results of calculations | Equivalent AC DWV : | ___ Volts |
| Arc Distance in Air (min): | ___ inches (___ mm) | |
| Arc Distance in Air (max): | ___ inches (___ mm) | |
| Arc Distance in Helium : | ___ inches (___ mm) | |
| Discussion | Your Dielectric Withstand Test uses ___ Vdc (or ___ Vac). If the test passes it will confirm that the smallest gap between exposed conductors in the cable is likely greater than ___ inches (___ mm). If the test fails you may have a gap less than ___ inches (___ mm). If the DWV test is done in helium then the test might detect a gap as large as ___ inches (___ mm). | |

Notes: The "Arc Distance in Air (min)" calculation is based on empirical data for a sharp point arcing to a plane. The "Arc Distance in Air (max)" calculation is based on empirical data for a plane arcing to a plane. The "Arc Distance in Helium" calculation is based on empirical data for a sharp point arching to a plane in a helium atmosphere. Both calculations are for standard pressure (760 mmHg) and room temperature (72 °F, 22.2 °C).
