Western Power Distribution is still not sure of the cause of a series of small power cuts in Horrabridge on Tuesday.
The company, which runs the power line networks, said today: “At 2:22 yesterday afternoon, we had a fault on the network which caused a supply interruption to 1762 customers for 11 minutes. At the time, we understood all customers were reconnected. Between 5pm and 6pm we had a call from a customer in Furzeland” (Grenofen) “who had no supply. Further investigations near the property found a faulty transformer affecting this one customer. The customer has a temporary generator supplying the property and repairs will be completed today.”
Horrabridge residents reported at least two other blips in supply during the morning, requiring resets of computers and electronic clocks.
Western Power said: “Fluctuations in supply can occur before a main fault becomes obvious.“
But the main fault is not yet explained.
The company has said before that its systems are designed to self-heal to some extent, so faults are sometimes hard to trace.
