ABSTRACT: This paper studies on the Partial Discharge (PD)
Locating System based on a mobile array of ultra-high frequency (UHF) antennas
and a vehicle-mounted PD locating system is established. The system consists of
omni-directional antenna array for receiving UHF PD signals, a pre-processing
circuit for signal amplification and filtering and the high- speed
acquisition and control unit of PD pulse signals. The developed locating system
is able to simultaneously record the PD pulse signals received by the antenna
array. By assessing the time difference of arrival (TDOA), the two-dimensional
hyperbolic locating model quickly locates the PD source. Based on the software
developed by LabVIEW, it is also possible to display, store and further analyze
the acquired signals. Through the simulation of PD signals and the locating
experiments with the system, it is proved that the PD locating system possesses
the features of rapidity and precision in determining the bearing of PD source.
