Sir today I have done 2 nos distribution transformer sfra test. I have one question while taking Lv side graph in distribution transformer,graph started from 0 db. Is it correct
First check, what is the temperature of winding, if temperature raised above set value.take precautions to down the temperature.and check cooling system, like fan,heat exchanger.
Can u tell me reason why open circuit plots are started between 30 db and 40 db . Shortcircuit plots are started from 0db and LV plots are started between 10db and 20 db
Very nice sir.. Nice explanation
