It’s Quieter Up Here – Partial Discharge Testing in the UHF Range #29

In this episode of Energy Talks, you will find out how partial discharge (PD) measurements performed in the ultra-high frequency (UHF) range can be a reliable alternative or complementary PD detection approach in noisy onsite testing environments. 

The conventional method for PD measurement according to the IEC 60270 standard allows a precise calibration but requires a sufficiently high signal-to-noise ratio (SNR) in the measurement circuit – this is however very difficult to obtain when performing PD measurements on site.

OMICRON PD application expert Ulrike Broniecki discusses how PD testing in the UHF range – such as with our UHF 800 system – can help you obtain a better measurement signal-to-noise ratio for reliable insulation condition assessment and defect detection in noisy testing environments. She also highlights the benefits of using the UHF PD measurement method on gas-insulated switchgear (GIS), gas-insulated lines (GIL), oil-filled transformers and high-voltage power cable terminations.
