High Voltage Protection Refurbishments

Northern Powergrid / Various Substations throughout the north east


Idec Technical Services were responsible for the replacement of all obsolete primary protection and auxiliary relays associated with long established substation switchgear sites. Provision of proven recent technology microprocessor protection relays fitted and pre-wired off site to panel fabricated fascias to minimise system feeder overall outage period for installation, testing and commissioning. work at numerous substations throughout the north east.

The design included the protection scheme specification and procurement of protection relays, panel components, panel metalwork and installation materials, preparation of scheme drawings, wiring diagrams, metalwork detailing, provision of installation documentation, site work programme, method statements, risk assessments, test schedules, wiring test sheets, commissioning test records and 'As Commissioned' documentation.

At programmed work location and applicable protection panel redundant protection relays and associated wiring removed. Panel metalwork modification content undertaken either by 'Plasma' cutting techniques at vibration sensitive panel suites or direct metalwork cutting performed at stand alone panels. Panel front plates mounted and pre-wiring connected to internal panel components and terminals.

On installation completion panel functionally tested and commissioned with Northern Powergrid in attendance.
