hi
2nos. of 5MVA and 2nos. of 2.5MVA DRY TYPE TRANSFORMERS are installed in the 26 x 6 m room.
i would like to natural ventilation is adequate or any additional ventilation to be required for this area.
let me know what IEC which refers the ventilation arrangement of transformer and...
Dear All
i am designing a Distribution system having one 2MVA 22kV/415V Transformer and one MAIN DISTRIBUTION BOARD (MDB) and 5 Distribution Board (DB). i obtain 40kA Fault in Transformer secondary and in every DB the Fault level is more than 30kA.
I want to reduce the Fault current level less...

Dear all,
I am doing the design of 220kV/66kV 100MVA substation.
short circuit MVA = 20000MVA
X/R Ratio = 34.1
short circuit current = 52.486kA
From the above i want to know how to calculate %Resistance(R) & %Reactance(X)
Kindly help me
Thanks & Regards,
LSK
