High Voltage Inspection Testing

High Voltage Inspection Testing
High Voltage Inspection Testing

High Voltage Inspection Testing for clients’ high voltage substations across the UK. The scope of work includes inspecting the tripping batteries and charger, visual inspection of all substation equipment, checking of the building security and testing the transformer insulating oil samples.

We are able to develop and implement comprehensive high voltage inspection, testing and maintenance strategies in order to mitigate the risk of an unforeseen breakdown or safety related issue.

C&P can set out comprehensive control operation and maintenance agreements in order for our team of high voltage electrical specialists to carry out testing and maintenance and act as SAP (senior authorised personnel) as part of your extended team.
