Anyones lecky in Luton going on and off for a second them coming back on. Done it twice tonight causing my neighbours house alarm to go off for an hour at a time.
Is the outage as long as 1 second? If it's just a brief dip then it's probably caused by a fault elsewhere on the network. The passage for fault current causes a voltage depression across the whole area which wil be seen as a big dip in the lights. More severe dips can cause eg computers to switch off. The first dip would have been the initial fault. Any subsequent sips will be caused by the process of sectionalising the network to find the fault. These subsequent dips SHOULD be less sever because we alter the protection settings to minimise the disruption.
Strange that 2nd would be more severe. Maybe the first fault caused severe damage to apparatus meaning that subsequent reclosures provide lower impedance paths for fault current - greater currents flow and voltage dip is more severe. Could be any number of reasons really.
I guess it could be a case of the grid in some areas possibly needing upgrading? (I know in my area they've built several thousand new homes, and don't seem to have done much thinking about how it affects the town in other ways - we've not got additional cops/many additional GP's/dentists considering the number of new houses).
I live down the road in Leighton Buzzard, and our lights have dimmed several times this evening - not enough to reset the computers though.
