Transformer Repair Services
The transformer which is the most expensive equipment in a switchyard/substation, is demanded to serve the entire life of a substation. Hence it is the most concerned asset in any utility companies. Global Power Test Sdn Bhd has the resources, besides investing in the mobile Oil Filtration Machine to undertake Transformer Repair services which include the following besides skilled in regasketing, repair & replacing of all accessories:-

By partnering with Select Solution of Australia, which has been accredited by National Association of Testing Authorities, Australia (NATA) is able to provide Transformer Oil Gas Analysis services to clients nationwide, providing assistance in diagnosis of transformer problems.Transformer oil can unfortunately be an overlooked maintenance issue.

  • DGA (Dissolved Gas Analysis) and Screen Test (Moisture Content, Acidity, Dielectric strength, Interfacial Tension & Colour) which is basically to characterise the Physio-Chemical of the Transformer fluid – Assessing the quality of the dielectric fluid.
  • Furan, Power factor, and Particles content
  • OLTC Analysis is important for all Power Transformers, as 50% of the Power Transformer failures are due to On Load Tap Changer (OLTC) failures. Therefore it is useful to determine the OLTC ageing process in an adequate and reliable way.

Transformer High Voltage Testing

  • Portable induced testing to 1500 MVA
  • Portable impulse testing to 525 kV
  • Portable no load and load testing to 800 MVA
