16 ENGINE ROOM WINTER EDITION “In November 2017, a mining customer suffered a mechanical tap changer fault, that caused one of their main transformers to explode. The loss of the transformer put a large amount of pressure on their back-up generator, which also suffered slight damage due to its proximity to the explosion and fire. With the lead-time for ordering a new transformer around five months, the client identified an unused 20MVA 11kV to 33kV transformer in an unused switchyard on their mining lease. Energising the spare transformer would reduce the pressure and high risk of failure on the back-up transformer. This is where EPSA stepped in with a RAPID DEPLOYMENT POWER STATION full turnkey temporary power solution under a competitive tender. Our team combined all internal capabilities - from electrical engineering and technicians to logistics and operations to ensure our client maintained fully operational. EPSA was awarded the project to supply 16 x 1500kVA generator 415v to 11kV for a period of 90 days to maintain the power station in full operation from late-January 2018. EPSA’s Rapid Deployment capability has resulted in responsive deployment of power stations around Australia by our rental team.” Terry Knott is the EPSA Rental Segment Manager for Queensland.
