The brief we were provided with was to design, build, install and commission a replacement set of 132kV and 33kV protection and control panels and carry out a protection change at the 132kV remote end substation (Bradford West) feeding the substation. In addition we were contracted to provide the new earthing system, design and install the new multicore cabling system and supply and install the interconnecting HV and LV busbars and structures to connect the transformer into the substation.
A very challenging programme of six weeks was set. This made necessary (with YEDLs consent) the temporary diversion of resources (materials and labour) away from other projects. A recovery plan was established for the projects from which resources were diverted.
Within 4 weeks a set of transformer protection comprising Biased Differential, HV Overcurrent, Standby Earth Fault 1 & 2, LV Directional Overcurrent, LV DAR, Low Frequency tripping and incorporating AVC were delivered to site.
Existing site master diagrams were modified to enable the equipment to be interfaced to the existing substation and installation work carried out enabling commissioning to commence to schedule.
