VAMVA TRANSFORMERS AND CONTROL

• he routine tests are performed on all the products and type tests on  request of customers.
  
  The routine tests for transformer are:
   

  • IR test
  • Separate square voltage with stand test
  • Winding Resistance measurement
  • Radio Party
  • Vector Group Confirmation
  • Induced over Voltage Test
  • No Load Current
  • No Load Loss Measurement
  • Load Loss Measurement
  • Over Voltage excitation characteristic on request
  • The temperature RISE test
  • SHORT Circuit with Stand Capacity test
  • Lighting Impulse voltage with stand test and temperature RISE test is performed In House Test at National Test Hose.

  
  For Reactors the Routine test conducted at our works are:-
   

  • IR Test
  • MV Test
  • Window Resistance Test
  • Total Loss Measurement
  • Inductance Measurement by V-1 method

  
  Also the over current test as per our standard to check and audible noise level. The Temperature rise test as a type test also can be conducted at our works upto 2000 A.
  
  Our test lab is fully equipped with the latest instruments, Duly calibrated, along with necessary intermediates, the complete unit is suitable to test transformers upto 36 kv/5000 kva and current injection upto 2000 a with 3 phase well balanced square (i.e all phases shall have the equal voltage) The unit is built measurement facility of all kind of transformers and reactors. the variable DC power supply us, that can be used for measurement of contact resistance, heat run test of DC Reactors etc.
