Power Transformer Installation & Commissioning


 

Our team of Transformer Technicians have a over 60 years’ experience Installing & Commissioning Power Transformers and Reactors across the world for all the leading OEM’s within the Power Utilities Industry.

This experience makes GTR Transformers an extremely competent and safe transformer Installation & Commissioning contractor.

Complete transformer installation assembly & initial offload supervision

GTR Technicians are competent in overseeing the Transformer offload from haulage contractor to final positioning to the sub-station plinth. Analysing Impact recorder data and performing core insulation checks is a given. Positioning Anti-Vibration pads and video recording the jacking down process is all part of what we do.

GTR Transformers’ Engineering knowhow provides its clients with the comfort & reassurance that its product is being handled with care by consciences Technicians.

 

Installation

Our Technicians coordinate all ancillary deliveries including safe operation of cranes/telehandlers before the assembly pre-checks commence.

During the installation GTR Technicians work to strict safety instruction detailed within Method Statements and Factory assembly protocol. Risk is mitigated and reduced prior to any shift by means of site-specific RA. Site conditions within outdoor sub-stations change hourly, risk is therefore continually monitored.

GTR Transformers’ Engineering knowhow provides its clients with the comfort & reassurance that its product is being handled with care by consciences Technicians.

Assembling cooler banks, pipework, conservators, turrets and bushings, Current Transformers, OLTC, ancillary components, kiosks and field wiring is all part of Technicians duty. Experience brings efficiencies which help our customer field installation budgets.

Documentation and Reporting

 

  • Customer Specific commissioning test documentation
  • Customised and system specific test documentation
  • Detail report on work completion with test results and further recommendations
Maintenance

The main purpose for all the above routine and maintenance tests and analysis is to detect transformer developing faults before a major failure occurs. In case of a major fault the only system that will isolate the transformer from the network and prevent from further extensive damages is the protection system. GTR specialises in testing and commissioning of protection schemes and protection relays and conducts secondary injections using specialised test equipment with dedicated transformer protection function modules. GTR also performs overall function testing to verify overall system integration, including mechanical trips from transformer protection devices.

Oil Sample Tests

As transformer oil is contact with every internal component of a transformer it contains a great deal of diagnostic information.

GTR can assist in conducting laboratory analysis of transformer oil samples to provide an advance warning of developing fault conditions. Standard supervision and maintenance analysis include tests such as dielectric strength, water content, acidity, colour, odour and visible contaminants.

Experienced staff GTR will rigorously test and compile comprehensive test reports post installation.

The Oil fill element is so critical to a Transformers longevity of service that such activity is continually monitored. Our senior Technicians are competent Oil plant operators and therefore skilling to diligently supervising oil plant contractors in making sure exact factory protocol is followed.
