Description
| - This article describes the partial discharges (PD) detection and localization system. Localization can be performed on the basis of measured UHF waveforms analysis during activity of the partial discharges. The time-shifts of the waveforms related to transient process occurrence in the signals are the main input parameters for localization methods. In order to estimate the position of the signal source in the 3D space a minimum of four antennas has to be used, since the time of the PD is unknown. Analysis of the PD starts with visual investigation of the signals present inside of the power oil transformer. PD signal level is in comparison to other signals inside the transformer very low. Therefore, signal line contains, except amplifiers, also controlled attenuators to reach required trigger conditions. Detailed investigation of all signals inside transformer is provided in memory mode in which system store defined number of signals for offline diagnosis a localization. Continual and memory mode of th
