Transformer Testing

The key to extending the lifespan and enhancing the performance of transformers rests on two main factors. The first is regular testing to ensure the optimal condition of major components. The second factor is preempting breakdowns to prevent severe and expensive damage to critical parts.
 
Motwane offers the following solutions:
  • Oil breakdown Voltage test
  • Oil tan delta & Resistivity test
  • Winding Resistance Test
  • Turns Ratio Test
  • Tan delta & capacitance test
  • Diagnostic Insulation test

Oil Insulation Test

Transformer Oil Testing is a proven loss prevention technique which should be a part of any condition based predictive maintenance program.Transformer oil acts as liquid insulation & dissipates heat of the transformer. It also helps to preserve the core and winding as these are fully immersed inside oil. Oil Breakdown voltage & Tan delta test results indicate health of the transformer which can allow maintenance management to identify maintenance priorities to avoid any major breakdown.
