Routine Maintenance and Inspection Service

Routine Maintenance and Inspection

Routine maintenance of high and low voltage plant should be carried out not simply to ensure reliable and economical service, but to comply with the provisions of the Health and Safety Executive. In addition, all maintenance and inspection is carried out as recommended by the equipment manufacturers and as required by BS 6626:1985 Code of Practice for Maintenance of Electrical Switchgear and Control Gear. Such works are implemented in compliance with the Electricity at Work Regulation 1989.

Only trained, competent, Authorised and Senior Authorised personnel are utilised by PWB Power. Our Engineers and Technicians are fully conversant with all varieties of electrical equipment, not to mention the differing handling, storing and disposal requirements.

PWB Power, also cover commissioning, testing and fault location.

Partial Discharge Testing Service

Partial Discharge Testing

Partial Discharge testing is used to analyse the presence of any electrical discharge within areas such as cable termination boxes, busbar chambers and switchgear enclosures, and is a non-intrusive test which can be carried out by competent persons with substation access without the need for a power shutdown.

Thermographic Survey Service

Thermographic Survey

Thermographic testing has become an accepted method for diagnosing potential faults. This system of analysis is particularly useful when it is difficult to arrange power outages, as it is necessary to have the system live in order to detect high resistance joints. A comprehensive report is produced highlighting any anomalies that are found.
