Transformer and switchgear refurbishment work

Services

Beyond equipment supply, we provide testing, assessment, refurbishment, and consulting services that extend asset life and de-risk capital decisions.

01

Transformer & Switchgear Oil and Gas Testing

Condition data is the foundation of safe operation and planned maintenance. Our testing services help clients understand insulation health, dielectric condition, and operational readiness before faults escalate.

  • Transformer oil testing and analysis
  • Switchgear oil testing
  • Gas testing (including SF₆ and related media)
  • Diagnostic reporting with clear next steps
  • Support for compliance and insurance requirements

MV Testing

Medium-voltage equipment testing verifies that switchgear, transformers, and protection systems perform safely and to specification — before energisation and throughout the asset lifecycle.

  • Medium-voltage equipment testing
  • Insulation and dielectric condition verification
  • Operational readiness checks before energisation
  • Diagnostic reporting with clear next steps

Facility Conditional Assessments

We conduct facility conditional assessments that give owners and operators a structured view of electrical and electromechanical assets — prioritising risk, remaining life, and investment sequencing.

  • On-site condition surveys of power and drive infrastructure
  • Risk ranking and remaining-life commentary
  • Recommendations for repair, refurbish, or replace
  • Input to capital planning and maintenance budgets

Transformer & Switchgear Refurbishments

Where assets retain structural and magnetic integrity, refurbishment is often the most cost-effective path to restored reliability. We manage transformer and switchgear refurbishment programmes with clear scope, quality checkpoints, and return-to-service criteria.

  • Transformer refurbishments
  • Switchgear refurbishments
  • Component replacement and reconditioning
  • Post-refurbishment testing and handover

Technical Consulting

Specifying specialised electrical and mechanical equipment is rarely a catalogue exercise. Our consulting support helps clients define requirements, evaluate options, and avoid costly mismatches between equipment and application.

  • Equipment specification and application guidance
  • Supply-chain and sourcing advice for specialised plant
  • Technical input to tenders, upgrades, and expansions
  • Independent review of proposed solutions
