Answer / e.saravanan

The change in secondary voltage from no load to full load
to the no load voltage is called regulation


= Vnl-Vfl/Vnl X 100

Answer / vinayagam

Regulation:means output voltage remains constant even when the Input Line voltage varies(130 to 300 volts).

Answer / bala

REgulation means: Maintain the supply voltage in specified
level by increasing or decreasing tap in power transformer

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?

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
