Phase-Phase Switching Overvoltages, Transmission Lines
2018Phase-phase insulation naturally occurs in stations—between buses and from one piece of equipment to another. Therefore the phase-phase strike distance and SSFOR should always be considered in station insulation coordination studies. A phase-phase insulation always exists with a phase-to-ground insulation.

Reduction of Switching Overvoltages in EHV and UHV Systems
IEEE Transactions on Power Apparatus and Systems, 1971The reduction of switching overvoltages by means of synchronized circuit-breakers with pre-insertion resistors is studied. The influence of system and breaker parameters is ascertained. The study shows that the reduction obtainable in a shunt-compensated system is sufficient for future UHV applications.

The overvoltage modeling on substation with valve discharge switch
2010Рассмотрен вопрос расчета перенапряжений в узловых точках подстанции с вентильным разрядником методом бегущих волн. Разработан алгоритм численной модели графического решения нелинейного дифференциального уравнения, что позволяет построить графики изменения напряжения в узлах подстанции.
