how can we minimize the off load losses of a distribution transformer which is required to be energized 24x7 ?? capacity of the T/F is 1250 KVA and off load losses are around 2.0 KW.. can we use capacitor bank at the secondary of such a T/F to overcome off load losses? please elaborate briefly...thanks
