Case Study

Replacement of LV equipment

Scheme Replacement of LV equipment
Location 1 Future Walk, Chesterfield, Derbyshire
Completed August 2017

RJ Power Networks carried out the safe removal, disposal and recycling of all the old equipment and then installed, tested and commissioned a new LV panel, power factor correction panel, battery tripping unit, remote generator connector panel and all containment and cabling, including the provision of health and safety file at 1 Future Walk in Derbyshire.

Following the failure of their Power Factor Correction section of the LV Switchboard, the client invited RJ Power Networks to tender for the replacement of the existing equipment. As part of the competitive tender process RJ Power Networks was one of three specialist market leaders in the power industry invited to quote for the works.

In addition to providing a competitive quotation and innovative technical solution, RJ Power Networks’ long standing relationships provided the necessary confidence to both the network maintainer and the client, which led to RJ Power Networks being awarded this prestigious contract.

Project Deliverables

The overall objective of the project was to replace all the equipment to the very latest specification with the minimum of disruption and to a fixed programme in order to minimise the running of the building off a temporary generator supply.

RJ Power Networks proposed solution included the following works:

The Challenges and Solutions

Due to the project time scales the planning, programming and coordination of the works was jointly carried out by the client, network operator and RJ Power Networks, which involved several workshops being organised to ensure that all aspects of the project were covered and agreed well in advance of the commencement on site.

In addition to the enabling and pre-installation works, the RJ Power Networks team and the network operator worked over two very busy weekends to carry out the changeover works from mains power to the temporary power in order to enable the old substation equipment to be removed, and changeover from the temporary power back to mains after the installation of the new substation equipment and reinstatement of cabling.

As the existing cables were to be re-used, the new switchboard was designed and manufactured to match the cable connection positions of the original switchboard. This was also made more difficult due to restricted access for installation of the new switchboard and the logistical challenges that this created. In order to combat these challenges, the new Switchboard was designed and manufactured 300mm smaller in height than the original.

RJ Power Networks was delighted to have the opportunity to work once again with one of their longterm clients and enjoyed working with new people within the client’s team. RJ Power Networks and the client continue to build and strengthen their relationship.
