HV testing & commissioning
Commissioning is the structured process of proving an electrical system is installed correctly, operates as intended, and is safe to energise — backed by test evidence and documentation.
What the service is
HV commissioning/testing commonly covers parts of the system such as switchgear, transformers, cables, protection and control, metering interfaces, and interlocks. The detail depends on scope, voltage level, asset type, and the standards and procedures the project must meet.
Who typically needs it
- New builds or major modifications (industrial sites, renewables, utilities, substations)
- Replacement of switchgear/transformers/cables
- Protection and control upgrades, or changes to interlocking and operating sequences
- Projects with formal handover requirements (test packs, witnessed testing, energisation gates)
What a typical engagement includes
- Review of drawings, asset schedules, and manufacturer documentation
- Commissioning plan / method statements aligned to site rules and safety requirements
- Functional checks, interlock verification, and point-to-point testing (as applicable)
- Protection and control testing (scope depends on relays, schemes, and interfaces)
- Compilation of test records, results, and handover documentation
What to provide for a quote
- Single line diagrams and latest drawings (or a clear description if drawings aren’t ready)
- Asset list: switchgear, transformers, cables, relays, meters, panels
- Voltage level(s), interfaces, and any customer/utility witnessing requirements
- Programme constraints and outage windows (if relevant)
- Site safety rules, access constraints, and authorisation requirements
