how kva rating of transformer is calculated.
Answer Posted / ashish patel
My dear friends,
First of all i want to introduce myself as transformer engr
having 12 years of experience in transformer field. Now in
reply of your question, if u r asking about Name Plate of
transformer, VA = 1.732 * V * Amp
Suppose In Name Plate,
HV Volts mentioned 11000 V, HV rated current mentioned 5.25
Amp, Than Transformer capacity is
1.732 * 11000 * 5.25 = 100023 VA = 100 KVA.
In the same name plate,
LV Volts mentioned 433 V, LV rated current mentioned 133.34
Amp, So Transformer capacity is
1.732 * 433 * 133.34 = 99999 VA = 100 KVA.
If you are asking about to decide transformer capacity, u
hv to calculate your total load + future expansion load.
Than you can take decision about ur required transformer
capacity.
