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?
Why we make earth connection with Transformer Body and What will be the minimum size of copper wire as per code with respect to KVA rating of Transformer?
If we use 250A MCCB as a incomer in Control panel for a fault level of 50kA for one second ,assuming temperature rise from 85 Deg. to 100 Deg , Then what will be the Aluminium Bus-bar size for 250A MCCB? Explain in detail.
