how we can calculate the transformer size.
Answer Posted / sanjay
The transformer sizing depends on (i) Continuous load +
(ii) Intermittant Load + (iii) 30% spare capacity.
With this you will get the required KVA size of the
transformer. Apart from this the consideration shall be
also on the type of load that the transformer shall feed.
In case of motor consideration shall be given to the
loading during starting of the biggesr motor along with hoe
many motors to be started at any one time.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs.
