Transformer Testing and Condition Assessment.


Picture
Assessing the condition of your transformer and making the decision about whether it is healthy enough to operate reliably is difficult. Testing your transformer after installation or during annual maintenance will allow you gauge or detect any unforeseen change in the condition of the transformer and take necessary repairs. We offer comprehensive transformer testing and assessment after installation or during maintenances such as. 
  • Transformer primary tests: insulation power factor, turns ratio, winding excitation, insulation resistance, winding resistance, sweep frequency analysis, leakage reactance, CT saturation and ratio and dissolved gas analysis
  • Transformer functional checks such as mechanical trips (Bucholz, Pressure relief devices and electronic thermal monitors)  and Load tap changer 
  • Testing and configuration of power transformer Protection relays functions (Overcurrent, earth fault, differential protection) and OLTC control relays.
  • Performance of predictive maintenances: oil levels, oil sampling and analysis, N2 pressure, temperature readings, visual inspections, Infrared thermography, ultrasound and Load tap changer inspection

Transformer Oil Filtration


Picture
Transformer oil is in an environment that leads to degradation of its desired properties over a period of time. When in service, transformer oil can be contaminated by particles, water, gases and chemical products and when not attended to can result in expensive transformer overhauls. We provide complete oil filtration and testing services to extend the operational life of your transformer. Our oil filtration removes and treats suspended solids, dissolved water, dissolved air and organic gases by utilising our state of the art vacuum dehydration units. We:
  • Drain Oil from Transformer
  • Store Oil On-Site in Tanks
  • Pull Vacuum on Transformer
  • Vacuum Degasify and Dehydrate New or Used Oil
  • Provide a comprehensive transformer oil analysis report for your maintenance reviews.
​Our specialised transformer oil filtration and testing engineers and technicians are available with the latest equipment and tools to handle your transformer oil filtration needs.

Transformer Maintenance


Picture
​Maximum availability of power transformer is crucial to a reliable power supply. As a transformer ages, its probability of failure increases. With proper maintenance, a transformer can continue to provide reliable service far beyond the average transformer life expectancy. Whether performing annual maintenance or repairs on your transformer, our experienced experts will support you with repair services such as: 
  • Gasket replacement, Bushing gasket repairs and change-outs
  • Bushing and lightning arrester replacement.
  • Welding repairs.
  • Pump repair and replacement.
  • Radiator replacement.
  • Replacement and repair cooling fans.
  • OLTC maintenance and retrofits..
  • Cleaning of transformer windings​.
  • Corrosion, rust removal and painting work.
