The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]
Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...
