how much load should be given on 5 mva transformer
Answer Posted / javad
Transformer have an interesting characteristics ie
You can Load the transformer around 20 % of Full load to
around 120% of full load without any problems(At that time
efficiency lie between 75 to 95 %).But maximum
efficiency will give when copper loss equal to core loss that
is around 80 to 85 % of full load.just see load vs efficiency
curve, then u ll b more clear.
