On November 30th, 2023 we were pleased to meet the technicians and management of Enel Peru to provide them with hands-on field training, as a follow-up to the (2) UltraTEV Plus 2’s they purchased. With us was Rosa Tipacti, Electrical Engineer from Logytec S.A., our long-time distributor for the Peruvian market.
EA Technology, specialist in asset management solutions for owners and operators of electrical assets, has launched an innovative new accessory for its UltraTEV® Plus² instrument for partial discharge (PD) detection. The new Wireless Phase Reference (WPR) unit makes PD data analysis easier and more accurate by helping to ensure a high-quality phase lock. The compact and robust WPR unit … Read more

Understanding the optimal partial discharge (PD) testing frequency is key to maintaining the health of high-voltage (HV) equipment. Regular PD testing helps identify insulation defects early—before they escalate into costly system failures. What is Partial Discharge and Why Does It Matter? Partial discharge refers to a localised dielectric breakdown of a small portion of electrical … Read more
Air Gap Partial Discharge (PD) is caused by a wide range of factors, including poorly fitted insulating materials such as boots, grommets, tie wraps, and sleeving. These materials seem harmless because they are insulating, but can cause PD instead of preventing it. Figure 1: Air Gap Causing PD Example Partial discharge is a tricky thing … Read more
On September 19th, 2023 we were pleased to provide in person training for employees of UTE, Uruguay’s national electric utility (Administración Nacional de Usinas y Trasmisiones Eléctricas). The training was conducted on the UltraTEV Plus 2 Kit 2 and UHF Directional Antenna Upgrade that the UTE division Parques Eolicos (wind farm) purchased. Conducting the … Read more
Partial Discharge is a poorly understood phenomenon, and it is even harder to understand because many different units are used to measure it. Making matters worse, sometimes you have to calibrate a test set up, and other times you don’t. This article will explain the various units, when and how they are used and why … Read more
Global electric car markets are seeing exponential growth as sales exceeded 10 million in 2022. This is expected to continue strongly throughout 2023 following an expected 35% year-on-year growth. As EVs become more commonly seen on the roads, the need to reinforce our existing power networks to accommodate the new demands arises. EA Technology is actively … Read more
Unexpected failures in medium & high voltage (MV/HV) cables cause significant losses in terms of downtime, safety, penalties, and availability. Most of these failures happen progressively and could be predicted from warning signs, most notably, partial discharge (PD). HFCT’s (High Frequency Current Transformers) are used to detect and measure partial discharge in shielded cables. Permanent installation of … Read more
