ELECTRICAL TRANSFORMERS

Tesar manufactures electrical transformers for more than 30 years. The range of production of electrical transformers covers power from 100 up to 3150 kVA and primary voltage up to 36 kV. Product quality is a priority for Tesar. The electrical transformers Tesar are subjected to rigorous testing to ensure the highest quality of products.

TESTING OF THE ELECTRICAL TRANSFORMERS

A particular attention is always given to the testing of the electrical transformers, which is done as per IEC 60076-11 standard in our two laboratories.
The routine tests are made on each transformer, while the type and special tests are done onthe prototype or on request.

ROUTINE TEST

  • Measurement of winding resistance
  • Measurement of voltage ratio
  • Measurment of short circuit impedance
  • Measurement of load losses
  • Measurement of no-load loss and current
  • Applied voltage test
  • Induced voltage test
  • Partial discharge measurement

TYPE TESTS

  • Impulse test
  • Temperature-rise test

SPECIAL TESTS

  • Measurmente of acoustic sound level
  • Recurrent impulse test
  • Environmental, climatica and fire
  • Behaviour test
  • Winding capacity test


  • Power transformers
  • Instrument transformers
  • Cast resin transformers
