UHF system for detection and spatial localization of partial discharge in high voltage power transformers
Original language description
The article presents a new approach to the detection of a very weak electromagnetic (EM) signal, which is generated by partial discharge (PD) in a high-voltage, oil-filled power transformer. The new technique is based on the discrimination of signals with origin in outside of the transformer which are detected by external sensing head. Performed measurement process contain several different measurement modes with corresponding arrangement of sensing heads. 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.
