The UltraTEV Locator™ is the product of EA Technology’s unique experience as a pioneer of measuring and interpreting Partial Discharge (PD) activity, gained over more than 35 years.

The UltraTEV Locator™ is a fully portable, multi-functional system for investigating and recording PD activity in unprecedented detail. It comprises a central unit with multiple sensors and dual probes, plus a range of accessory options to increase its versatility even further.

The accuracy and versatility of the UltraTEV Locator™ derive from employing six sensor technologies in a single package. The addition of sensors which measure environmental variables which are known to affect PD activity greatly increases the value of measurements.
