چکیده مقاله:
Power transformers are one of the most expensive components of the power system. Timely detection of fault arose in the transformer can be used to prevent unwanted outage oftransformer and repair costs. Using electromagnetic waves has recently been proposed for on-line monitoring of thetransformer. The presence of the tank in the transformer structure causes problem for analyzing the electromagnetic waves. In this paper, a new analytical method based on locusof the objects in the space is proposed to detect the radial deformation location of a disk winding considering tank effect.The proposed experimental set-up for this method has been modeled using CST (Computer Simulation Technology) software. In this paper, Vivaldi antennas suitable for measurements in environments with multi-path routing are used and the analysis is performed in the time domain. Thesimulation results show that exact determination of radial deformation location can be detected with good accuracy usingthis method.
