what is the significance of KV & MVA rating of the
transformer and how they are related.
Answer Posted / subra
In power transmission operating voltage are in K V
ie Kilo Volt
The transformers Capacity is in MVA ie Mega Volt Ampere
In power Distribution Network operating Voltage in KV kilo Volt
The transformer Capacity in KVA
Power in 3h = Root3 VxI ---VA
root 3VxI Cosphi----Watts
watts X 1000 =KW VA x 1000 = KVA
Watts x 1000000 = MW KVA X 1000 = MVA
