Abstract
The results of research into the causes of accidents linear gas-insulated switches commutations in compensated 750 kV overhead lines. Recommendations for prevention accidents due to the ongoing unconnected pole of gas-insulated circuit breakers that do not pass through zero due to presence of a large aperiodic component are formulated. In the paper abnormal modes EHV transmission lines with varying degrees of compensation charging capacity are performed. Electromagnetic processes in compensated power lines, depending on the initial conditions at the time of switching are investigated. The points of abrupt change settings of transients while switching high voltage lines are identified. Measures for limiting the duration of the existence aperiodical component of current have been considered. References 5, figures 2, tables 3.
