Our engineers

Our engineers are available nationwide in the event of loss of power and we also carry out cable location and fault finding to ensure the issue is rectified as quickly as possible. We also have a large stock of transformers and switchgear at our unit in Leeds, removing procurement lead times to minimise site disruption.

Test

Partial Discharge Testing

Partial Discharge (PD) is widely regarded as the best early warning indicator of the deterioration of high voltage equipment. We, therefore, offer an optional PD service on all our maintenance contracts to indicate any incipient faults in HV insulation.

Supports condition-based maintenance
Avoids unplanned outages and improves network reliability
Obtains baseline PD readings to evaluate insulation and installation quality
Increases safety – mostly with switchgear, outdoor HV plant, and cable sealing ends
Extends asset life, delaying capital replacement (ageing population problem)

Protean Software experts

All maintenance inspections are completed digitally through Protean software, with data automatically transferred to our head office for analysis and reporting. Customers can receive immediate job sheets, while final reports clearly flag pass/fail results, outline required remedial work, and include copies of all inspection records to ensure safety and compliance.
