A fast resolution to power outage at GTR Selhurst depot

When it was reported to Hollywell that one of the four transformers on site was down, Hollywell had two engineers on site within two hours and it was soon obvious that the problem was not going to be a simple fix and some lateral thinking was required.

The triangle of land that forms the Selhurst depot is bordered by the extremely busy lines going into London Victoria and London Bridge stations. It was built on a piece of land that in the early 1920’s was home to the ground where Crystal Palace FC played their matches and now is where many of the train crews in the region are based.

During the initial inspection of the faulty generator it was clear to our engineers that the problem was going to take some time to resolve and the decision to install two 300kVA three phase generators was quickly made.

Back at Hollywell’s head office in Hertfordshire, the generators were sourced and they were delivered to site that same day. Power was quickly restored later that day and then a more thorough investigation on what had caused the failure could be made.

The problem was diagnosed as being caused by a disturbance to the buried power cable leading to the generator by other works taking place at the site.

The two temporary generators stayed on site for another month whilst the damaged cable was safely replaced. During that time, Hollywell ensured that the generators were operating efficiently to ensure that no further disruption occurred.
