Powercomm offers full testing and commissioning services up to 400kV. Our skilled teams specialise in projects from unit substations in a commercial setting to larger transmission, distribution and generation plants for Utilities, power producers, data centres and renewable generation.
Our expertise covers all the different aspects of commissioning for HV/MV solutions from 3.3kV to 400kV, employing our state-of-the-art test equipment and diagnostic capabilities to assure excellent service results. Powercomm have developed a highly skilled commissioning team that have extensive knowledge and experience to carry out all stages of the commissioning process from point to point wiring checks, function checks to complex protection scheme testing.
We also offer commissioning consultancy/support using designated personnel to meet your specific requirements, providing specialist assistance with fault finding, electrical systems, technical guidance, commissioning witnessing and handover.
