Summary
UHF PD-measurements can be used in a wide frequency range up to some GHz. Many studies have been published in the past showing different maxima in the frequency spectrum depending on the setup. From the beginning of the UHF PDmeasurement, there is a discussion, how to find a relation between apparent charge at the measurement terminals and the characteristics in the frequency spectrum. This paper deals with HF-simulations and measurements of different PD sources such as different small needles and a potential free floating metal fragments in gas and submerged in oil. The paper investigates the influence on the frequency spectrum from different length and thickness of the needle. This evolves an influence on the discussion if an UHF PD-measurement can be calibrated.
