Drying and Filling

Timsan uses state of art furnaces and vacuum units to completely remove the moisture and air from the transformers. Transformers are brought to the test stage with filtered oil filling under vacuum.

Drying and Filling

Timsan conducts all routine tests and some type tests in its ISO 17025 accredited laboratories. Transformers are tested at international test centers at regular intervals.

Routine Tests

  • Measurement of winding resistances.
  • Measuring the turn ratio.
  • Checking polarity or connection group.
  • Measurement of short-circuit (UK) and load losses.
  • Measurement of core losses and current.
  • Inducted voltage test.
  • Measuring the insulation resistances.

Type Tests

  • Temperature rise for liquid-Immersed transformers.
  • Determination of sound levels.
  • Requirements and test concerning pressurized corrugated tanks.

Oil Test

  • Insulating liquids-determination of breakdown voltage of power frequency.(9)
