Radiometric PD Surveys
Radiometric partial discharge (PD) surveys are a rapid, safe and cost-effective
way to monitor high-voltage equipment. Surveys utilise PD location and data acquisition
equipment, installed in a vehicle that can be driven around a substation, surveying
all of the high-voltage equipment.
Surveys can be conducted in a few hours. Driven slowly around the substation, the
sensitive antenna array passes within a few 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 compared with an extensive database
of faults. We provide a detailed report for every survey, incorporating information
on PD activity, photographic evidence of the source and advice on how best to proceed.
