Sub-station explosion knocks town trade



An explosion at town centre electricity sub-station on Tuesday night forced businesses around Leigh Road to clse yesterday. The substation was located in the Sainsbury’s complex and the blast was felt by customers in the adjoining
Leo leisure Bingo hall.

The Ukip HQ on Market street was affected and they had to hire a generator to provide power for their last full day of campaigning.

    Obviously there was a MAJOR short circuit before the sub-station circuit breaker.

    Correct me if I’m wrong, but that sub-station is on the 11kv ring. Assuming a drill bit caused the short and assuming a resistance of 1 ohm, and ignoring arcing, then there would have been a momentary current of 11,000 Amps before a CB interrupted the power further down the line.

    The power (amps x volts) would have thus been 120 million watts or roughly 30 million calories per second.

    Assuming the discharge lasted for 1 second (although the CB would have kicked in quicker) then that’s enough heat to raise the temperature of a 136 lb man to boiling point in one second!

    I think the operative was lucky to get out of there alive.

    My question would be, why was someone drilling in or around a sub-station? Was this someone from Scottish Power or a contractor?
