Partial Discharge is a phenomenon that commonly occurs in overhead line insulators. It can occur for a number of reasons, which is where HV Diagnostics come in. We are a knowledgeable crew, who can get to the cause of any Partial Discharge issues.
As with the ground mount surveys, we offer condition assessment for overhead networks predominantly within High Voltage switchyards and often in conjunction with the Switchboard survey. We use three complimentary techniques – Ultrasonic (with Dish) for surface discharge, UHF for ‘internal’ activity and Infrared Thermography (using Guide Camera) for Hotspots and other thermal anomalies.
We understand that when it comes to Partial Discharge there are a range of sensor technologies and can easily assess and advise on what option is best suited to your situation. Utilising the right assessment method ensures the most effective results.
