Abstract: With the recent developments and improvements in Extra High Voltage (EHV), circuit breakers, over voltages caused by energisation or de-energisation of lines can be made so low that the limiting factor determining the reduction in the line insulation might be considered the overvoltage produced by single line-to-ground faults. On lines insulated for levels below twice the normal line-to-ground crest voltage, such faults could develop into double line-to-ground faults, which would be particularly objectionable if single-pole switching were to be employed. This paper presents a mathematical analysis of transient due to fault initiation at any point on the double circuit Extra High Voltage transmission system, using the Fast Fourier Transform technique.
Keywords: EHV Transmission Lines, Transient Over Voltages, Line-to-Ground Faults, Fast Fourier Transform.
