How to calculate voltage drop in copper and aluminium cable?
I have laid 240Sq.mm Aluminium cable for the length of 600 Mtrs in 1 Mtrs underground.
Normal load is 150A. Transformer is 630KVA, 6.KV/433V. But, I am getting only 395 Volts when load. How to calculate voltage drop and what is the permissible voltge drop for this circuit?
