Question

there are four individual transformer feeder having connected loads of 250 kva, 300 kva, 350 kva, demand factor of these are 80%, 70%, 75% and 90% respectively diversity factor is 1.6 find the total demand of load and size of transformer required to supply these loads

Answer 1

First, calculate the individual demand of each feeder circuit, by multiplying the value of the connected loads with their respective demand factor percentages. Add up these four values to get the total demand of the load.
The size of the transformer required given a diversity factor of 1.6 is the total demand divided by 1.6
