The MES team is currently undertaking core switchboard replacement work at Telstra’s London data center.

Project background

The MES team is currently undertaking core switchboard replacement work at Telstra’s London data center. Part of our four-year life cycle replacement plan, this work involves factory witness testing, which has recently been hosted by Mardix.

The Metropolitan solution

After successfully completing the replacement of switchboard L2m supplied from TX2 in 2019, MES is currently replacing switchboards L1 & LVP1 supplied from TX4 at the data center.

Specifically, this project involves replacing the two existing 3200amp LV switchboards and combining into one 4000 amp generator-backed LV switchboard with a standalone PFC section.

All devices are independently metered with the same setup as the switchboard replaced under phase 1.

And as all meters enable digital multiparameter c/w RS485 comms output, we can install a full, site-wide smart metering system as a separate day two project.

At the time of writing, switch room modifications are underway to facilitate the removal of the old switchboards and installation of the new ones. Site temporary supplies are in place and ready for the migration of the existing sub mains into the new switchboard.

By following a considered and carefully-planned approach, we have been able to deliver this project with minimal downtime to Telstra’s end users.

After a full day of testing, our new switchboard has passed an intense routine verification in accordance with BS EN 61439-2 and is set for delivery on 24th February 2020.

As expected, this project is running on time and is due for completion in May 2020.

Stay tuned for a further update on this in-depth project once the new panel has been delivered and installed.
