please give me solution to rectify the emi(electromagnetic interference)
FOR 16/20 MVA 132/33 KV ONAN/ONAF TYPE TRANSFORMER IT IS DESIGNED FOR 16 MVA WITH ONAN CONDITION.IT BECOMES 20 MVA UNDER ONAF CONDITION.LOAD LOSS IS GUARANTEED FOR 65KW AT 20 MVA AND % IMPEDANCE 13.75. PLEASE TELL US AT WHAT LOAD LOSS AND % IMPEDANCE IT SHOULD BE DESIGNED FOR 16 MVA AND WHAT WILL BE ITS EFFICIENCY AT 20 MVA?
