Northern Powergrid


PBO Relay Replacement


Protection Modifications


Carlton Hill Substation, Leeds

The Brief

The project proposed the replacement of time expired Type PBO and Type CDG and associated Type B26 protection relays with new modern numeric equivalents and the installation of a new communications ring to the RTU.

The Approach

Throughout the proposal stage of the project Freedom and Northern Powergrid worked closely together to develop the protection design and delivery schedule.

The Delivery

Freedom worked very closely with NPg Technical Services, Site Delivery Engineers and the appointed Project Manager. Changes to design were kept to a minimum due to this close working ethos and the ability to discuss potential issues throughout the proposal process. The Site Installation team were under pressure to meet the tight timescales for the project but they worked effectively as a unit and in conjunction with the NPg Commissioning engineer and SAP and to reduce the length of time required for each circuit outage. Weekly progress meetings were held to maintain the close working relationship between all parties and included regular positive feedback on the delivery from the client.
