The standard online partial discharge test modalities include TEV, Ultrasonic, and RFCT. An up and coming technology is Ultra High Frequency or UHF radio wave detection.
UHF radio wave detection is different and complimentary to the existing technologies. UHF is useful in applications where the other technologies may not work well or it can provide a second confirming reading to the existing technologies.
The use of UHF detection has different advantages and disadvantages and different techniques need to be applied. These need to be understood to properly employ this technology. UHF detection is a new PD test modality that might be useful in the test technician's stable of capabilities.
This presentation will cover the science and technology behind UHF detection. It will provide real world examples of PD found with UHF detection from the US, Australia, and the United Kingdom.
