how much loading in terms of ampere can put on 5 MVA,33/11
KV TRANSFORMER having rated current 263 Amp ?????????
Answer Posted / pravin
Actually it depends upon designer. If we asked designer to
designed for 125% overload, he will provide cooling per
current loading on 125% overload to restrict Hot Spot Temp.
of the winding & Top oil temp. respective to max. ambient
temp.
In this case, we can provide loading of 437A in
terms of ampere on top rating with Hot spot temp & top oil
temp in control on top rating. Actually transformer has
three rating OA/FA/FA. If this transformer is OA/FA/FA then
we can provide this loading.
If it is self cooled then 263A is max. loading.
