EA Technology, a global leader in grid-edge intelligence, has launched OLIMS, a new online platform designed to streamline the testing, monitoring, and maintenance of high-voltage (HV) electrical assets across the UK.
The OLIMS platform gives Distribution Network Operators (DNOs) and industrial site operators a single, centralised view of HV transformer oil test results, enabling real-time insights, easier trend analysis, and more informed maintenance decisions to improve asset reliability.
The platform is supported by EA Technology’s oil testing laboratory at its Capenhurst headquarters, which processes over 40,000 oil samples annually. Following a major expansion in autumn 2025, the lab has doubled its testing capacity to meet increasing industry demand.
Available nationwide, the service tests oil samples for key health indicators, including dissolved gases, moisture, and acidity, critical measures for assessing transformer condition and preventing unplanned failures. Regular oil testing is essential to reducing the risk of insulation breakdown, overheating, and power outages affecting commercial and domestic supply.

Jonathan Lewin, Head of HV Monitoring at EA Technology, said the platform will help operators stay ahead of maintenance needs.
“Oil testing is a vital tool for industry and DNOs looking to check the health of their network and stay on top of their high voltage maintenance.
“It’s pivotal in the day-to-day running of our national energy network, without which we put the electricity supply to our critical public, commercial, and domestic infrastructure at risk of failure.
“With the addition of our new OLIMS platform, we’re aiming to make it easier to keep on top of oil maintenance – a small but mighty part of keeping the UK’s power on.”
The launch of OLIMS reinforces EA Technology’s commitment to digital innovation and a more resilient, intelligent energy network.
