Tests

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)
