“We used Industrial Switchgear Services to test and commission two of the new Substation Switchgear Alliance Containerised Air Insulated Switchgear substations and ABB Autotransformers on the phase 4 NWEP route between Salford and Preston in 2017. ISS provided us with commissioning engineers and technicians to carry out various commissioning activities at Clifton ATS and Blackrod ATS which included Contact Resistance Testing, Current Transformer Testing, Voltage Transformer Testing & HVAC Busbar and Autotransformer Pressure Testing. The project has other substations, Autotransformers and HV cables that will need testing in the future once the construction works are complete. ISS are proactive in providing resources for the works and couldn’t be any more helpful. The service they provide is exceptional and very professional. They’re also very flexible when providing staff for the project. I can’t praise them enough for the service they provide”.
