Factory Test

For each transformer are prepared and issued a test report, in accordance with IEC 60076.  except for routine tests, we also offer type tests and specialised tests to meet all customer requirements. We make what matters work for our customers in a safe and reliable way.


  Routine test

 a) Measurement of winding resistance

 b) Measurement of voltage ratio and check of phase displacement

 c) Measurement of short-circuit impedance and load loss

 d) Measurement of no-load loss and current

 e) Separate-source AC withstand voltage test

 f) Induced AC withstand voltage test

 g) Partial discharge measurement


  Type test

 a) Lightning impulse test

 b) Temperature-rise test


  Special test

 a) Partial discharge measurement

 b) Measurement of sound level

 c) Short-circuit test


Applications

Indoor and outdoor, renewable generation,commercial, industrial and residential sites
