    I would say it is. They do make giant electricity things like that when they get turned on.

    Im not an electrician or electrical engineer though

    Read this feasible explanation somwhere else:
    And here is a 345Kv switch opening :)

    Yup, that is exactly what happens when switches that size open....i've had the 'unfortunate' experience of working on a 400kV one! :(

    Theres a fair delay before the switch is clear...

    That sort of only happens when it's opened under load, which shouldn't be done really as it can wear down the contacts. I think I remember reading somewhere that it was caused by a fault, but I thought most switches were submersed in oil anyway.

    It's normal for HV switches to be switched in oil (up to 33kv) when on load but in substation compunds and in remote places "air" is the prefered insulator as it's cheaper :) and dosen't require looking after. Also substation oil switches for 11kv can be closed on load/faults, this is when you have a long piece of string so that you are standing out of the substaion when you close the breaker in on the load / fault. In remote locations it's normal for the breaker to close in upto about 6 times automatically just in case it's a transient (sp) fault.

    on 11 and 33kv Mast switches should not be closed in on faults, for saftey reasons, however on 11kv nowadays you have smart fuses and links which work in fault conditions.
