Challenge
Customer was covered by our 24 Hour Emergency response and reported that their transformer had started to ‘lean’ and was still on the move. A responder attended site within an hour of the call and immediately switched the supply off remotely. Having made safe we needed to avert the potential environmental risk of breach of tank and 100’s of litres of insulation oil spilling into the water table, with Hiab and MEWP support, as the ground could not be deemed safe to walk on; we disconnected the HV/LV cables to allow for removal, in parallel we connected a generator to temporarily provide power so that production was restored.
Solution
During the site survey the current location for the Bowers transformer was confirmed non-viable for the replacement and a suitable place was identified for the new transformer.The responder discussed the current and future requirements for supply at site with the customer. The replacement Transformer was specified as a 1250kVA, replacing the original Transformer that was a 1000kVA. The existing HV network had to be altered and upgraded to accommodate the new location and ensure minimal disruption to site and keeping civils to a minimum to reestablish supply.
Outcomes
From power outage disaster to rectification within two weeks.
