The functional units of the ACBs will include protection, automation, measurement, counting, monitoring, diagnosis, and communications functions. An interface controller will also be provided to allow Merseytravel to connect to the control unit to change parameters, interrogate readings, and allow secondary injection simulation for future maintenance. The controller will have an RS 485 connection facility for future use.
SPIE has worked with Merseytravel for over 20 years, with the current framework agreement covering the last 5 and the delivery of six similar schemes. The work will require the specialist skill of a Senior Authorised Person to isolate and switch the specific power supplies. However, in doing so, alternative power sources also need to be maintained and provided.
Chris Mayoh, a Contract Manager at SPIE UK said, “We are glad to have been chosen by Merseytravel to help them upgrade the Air Circuit Breakers at the Sidney Street Ventilation Building. The 20-year relationship we have with Merseytravel is testament to the high-quality work we deliver continuously, and we are confident that the team will do a great job this time round as well.”
Colin Dever, a Technical Services Manager for Merseytravel, said, “SPIE UK has always proven itself to be a fantastic partner, so when we knew it was necessary to upgrade the ACBs they were a natural choice. It was critical to us that the new installation allowed for remote monitoring and SPIE’s expertise in this area gives us confidence that the new systems will meet our exact requirements and deliver value for money.”
