In this paper new method for transformer winding statement have been considered. The practical results of defect location in the insulation of high voltage equipment in laboratory and real substations conditions are presented and discussed. Theoretical background and technical implementation of the method of CPRA (Corona Pulses Response Analysis), designed to control the deformation of the windings...
Early detection of unacceptable increasing water content in transformer oil is a factor in reliability oil-filled equipment. There are various methods and devices to determine water content in transformer oil.
Due to increase in age of the power transformer park it is necessary to solve the problem a residual resource. Recently, with this purpose periodic inspection techniques of energized and off-line transformers are used to estimate technical transformer condition and to give recommendations on prolongation of service life. In this paper Transformer Diagnostics Monitoring (TDM) system is described as...
PD measurement is well-known method for inspection of high voltage equipment. However, its on-site application has some difficulties. This paper is dedicated to the calibration of PD measurement by electrical method; it is more precise, to the method of the introduction of charge into the tested object.
