Abstract

This paper presents a mathematical modelling of the transient processes in a capacitive take-off power network. This model is based on the calculation of magnetic flux of a single-phase, two-winding transformer. This model is represented by non-linear equations. The short circuit occurs along the steel core, and the leakage flux coupling the separated coils closes out the side of core. The mathematical model is developed to investigate the conditions of transient process analysis in a capacitive take-off power network. The reduction of overvoltage during short circuit period is also studied in this paper. Also, this paper suggests the solution manner using programme techniques. The final results and conclusions are presented.
