Megavar provides a complete range of plant testing and commissioning services to assure the technical, operational, reliability, safety and efficiency of power systems.  Megavar’s core expertise lies in testing and commissioning. We provide inspection and test plans, factory acceptance testing, site acceptance testing, pre-commissioning and commissioning services for new and upgraded equipment.  We test a system or plant to verify functional operation, in accordance with the system design and manufacturer’s specifications.

The commissioning team should be involved in the whole project, from design and construction through to operation. The more complex the high voltage system, the more critical commissioning becomes, for long term reliability and return-on-investment.

Commissioning is an important part of developing an ongoing preventive maintenance program. It gives you confidence to know your equipment will operate safely, and helps avoid downtime due to malfunction. Our commissioning tests provide the baseline data necessary to your asset monitoring and preventive maintenance program.

Our commissioning teams are outfitted with the latest in HV testing and commissioning equipment and are experienced with equipment from a wide range of manufacturers. We test and commission primary plant including:

  • Circuit breakers
  • Current transformers
  • Voltage transformers
  • Transformers
  • Disconnectors
  • Earthing systems
  • Insulation
  • Sweep frequency response analysis.
