Partial discharges measurement by UHF method

open access: yesZbornik radova Elektrotehnicki institut Nikola Tesla, 2020
The unconventional UHF (Ultra High Frequency) method of measuring partial discharges (PD) is based on measuring electromagnetic waves (EM) in the UHF frequency band (300-3000) MHz, using appropriate antennas. This method is unconventional, but is widely accepted due to the possibility of application in plants in the online mode and quick review ...
