We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
