how much load should be given on 5 mva transformer
Answer Posted / addicted to know electrical
Load means current,not Mw(power).So,by looking at
P=VI*p.f....
Since i is load which is always variable....the power drawn
from the transformer will always vary......and hence it is
not inour hand how much load shall be given to the
transformer but the efficiency will be max. when load is
equal to iron loss divided by square of secondary
resistance.

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
