an off load but energized 11/0.4 KV, 1250 KVA T/F has a
power factor of 0.65(capacitive)..!! why is it so, though
T/F being an inductive device ??
Answer Posted / doss
if its a new transformer please check the test report done by site acceptence tan delta test .its should be the capacitance high ,and dessipation factor also need to check ...
if the result is high means need to check the winding...if the tan@ reading is less than 0.05 the transformer is good condition..so check external..
