The service includes:

Scheduled (Preventive) Maintenance

Routine checks to prevent failures

  • Visual inspections: Check for corrosion, oil leaks, unusual noise, cracks in insulators.
  • Cleaning: Dust, salt, or bird droppings can cause tracking and flashovers.
  • Tightening connections: Prevent overheating and arcing at busbars, terminals, and grounding points.
  • Testing protective relays: Ensuring protection systems (overcurrent, differential, distance relays) work correctly.
  • Lubrication: Moving parts of disconnectors and circuit breakers.

Predictive (Condition-Based) Maintenance

Forecast issues before they happen

  • Thermographic inspections (infrared cameras): Detect hot spots in connections and transformers.
  • Oil analysis of power transformers: Dissolved gas analysis (DGA) reveals insulation aging or faults.
  • Partial discharge (PD) testing: Identifies insulation defects in cables and switchgear.
  • Online monitoring: SCADA systems track load, voltage, breaker operations, and alarms.

Corrective (Unscheduled) Maintenance

Fast response when needed

  • Replacing failed fuses, surge arresters, or transformers.
  • Repairing protection / control equipment after faults.

A strong mission for the future

Our mission is to advance renewable energy by transforming natural resources into sustainable power solutions.

Mission and Vision

ISO certifications

Including ISO 9001:2015 for quality management and ISO 45001:2018 for occupational health & safety, underscoring its compliance with international standards across quality, safety and environmental.
