Sparky Posted September 17, 2009 Share Posted September 17, 2009 A fault at a substation on the Isle of Man causes some homes and schools to go without electricity for a short time. Source : http://news.bbc.co.uk/go/rss/-/1/hi/world/...man/8254600.stm Which is entirely different to what the MEA reported on their website. "At 0923hrs this morning an incident occurred at an electrical substation in the Pulrose area which caused loss of supplies to a relatively small number of customers. Supplies are being restored through alternative circuits and this will be completed shortly. The impact of this fault will have been seen with a dimming of lights for a fraction of a moment across the Island. If any customers are still off they should firstly check their trip-switch if there is still no supply by 11am, they should call 687687 to report the fault. We apologise for any inconvenience caused and would assure customers that we are working as quickly as we can to restore all supplies." If all it caused was a dimming of lights why would they also say that if there is still no supply by 11am that you should call the MEA? Link to comment Share on other sites More sharing options...
Nitro Posted September 17, 2009 Share Posted September 17, 2009 It clearly says "The impact of this fault will have been seen with a dimming of lights for a fraction of a moment across the Island. " Ie those not in the Pulrose area would have seen a dimming of lights, however some of those in the Pulrose area had a power cut... Link to comment Share on other sites More sharing options...
Slim Posted September 17, 2009 Share Posted September 17, 2009 I think they're saying the impact for those not completely off will be a dimming of the lights while the supply is re-routed. Link to comment Share on other sites More sharing options...
Mutley Posted September 17, 2009 Share Posted September 17, 2009 Curiously there has been a lot of activity and a fire engine present at the substation on North Quay since this happened. Isn't that where the fault occured a few years ago when the power went pop the last time? Link to comment Share on other sites More sharing options...
bluemonday Posted September 17, 2009 Share Posted September 17, 2009 Do MEA facilities still use pcbs? I understand there are now greener alternatives. Link to comment Share on other sites More sharing options...
Tempus Fugit Posted September 17, 2009 Share Posted September 17, 2009 do we assume from the wording that the substation was not actually inside the power station at Pully, but out in the estate somewhere How long is a moment ?, we had a cut of about a quarter of a 'moment', enough to reboot any pcs not on a ups, reset some digital clocks but some survived. It also scrambled one of my routers which I use as a hub to feed a couple of pcs on the end of a long cat5 cable, appeared to be dead until I checked the power supply, took the case apart, by which time it had decided to burst into life again Link to comment Share on other sites More sharing options...

Albert Tatlock Posted September 17, 2009 Share Posted September 17, 2009 The high voltage stuff in sub-stations is switched by heavy spring-operated switchgear - encased and bathed in insulating oil. You don't want to be standing near one when it goes off, you'd sh1t yourself. On a fault, usually when you try and draw too much power on the remainder of the circuits, the voltage drops - and lights dim momentarily until the load is re-balanced. Sometimes when it has been raining very heavily on an outside substation, water can creep into the switchgear or a transformer contaminating the insulating oil and then - bnag!
