Chalfont

High Power and High Voltage Test Facility in US

Your #1 Resource for Electrical Testing

Our Lab offers many testing services including, but not limited to, high-power short-circuit testing both AC and DC, high-voltage testing, synthetic testing, thermal testing, impulse testing, and more.

The High Power Lab can generate short circuit values up to 245kV/63kA. The High Voltage Lab complements the High Power Lab with dielectric testing services up to 230kV. Combined, these facilities test virtually any device at the distribution and sub-transmission level in the US power grid.
