Related product parameters

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 loss

 d) Measurement of no-load loss and current

 e) Dielectric routine tests

 f) Tests on on-load tap-changers, where appropriate

 g) Leak testing with pressure for liquid-immersed transformers(tightness test)

 h) Tightness tests and pressure tests for tanks for gas-filled transformers

 i) Check of the ratio and polarity of built-in current transformers


 Type test

 a) Temperature-rise type test

 b) Dielectric type tests

 c) Determination of sound level for each method of cooling for which a guaranteed sound level is specified

 d) Measurement of the power taken by the fan and liquid pump motors

 e) Measurement of no-load loss and current at 90% and 110% of rated voltage


Applications

Step-up substation is designed as box type and specially for new energy generation industry, which can adjust the low voltage from inverter station to high voltage and then run in power grid. So a box-type inverter station and a step-up station can be integrated into one power generation station. It’s widely applied in Solar Energy Power Plant, Wind Energy Power Plant and Nuclear Power Plant, etc.
