Partial Discharge Detection Surveys
AIS radiometric partial discharge surveys are a rapid, safe and cost-effective way to monitor high-voltage equipment. Surveys utilise PD location and data acquisition equipment, either installed in on vehicle, on a backpack, or set as a fixed array, surveying all of the high-voltage equipment around it.
Radiometric partial discharge detector surveys can be conducted in a few hours depending on substation size. Moving around the substation, the sensitive antenna array passes within several metres of all high-voltage equipment, allowing the measurement and location of even relatively small levels of PD.
When activity is found, data is recorded and is analysed by experts in the field of PD. We provide a detailed report for every partial discharge detector survey, incorporating information on PD activity, photographic evidence of the source and advice on how best to proceed.
Surveys are also carried out on GIS switchgear, transformers and cables where it is possible to connect RF PD sensors.
