why do we generate only 3ph ac?is it possible to generate
4ph,5ph,....?

Answer Posted / a.kossay

BECAUSE THE 3 PHASE SYSTEM FOUND TO BE THE MOST ECONOMICAL
FROM OTHER TRANSFOMATION , IN SINGLE PHASE THERE WILL
ALWAYS BE MAGNETIC FORCES TRANSFORMER WALL WILL ALWAYS BE
HEATED, IN 2 PHASE SYSTEM IF A WIRE BREAK HAPPENS HALF OF
THE LOAD WILL BE DISCONECTED NOT LIKE THE 3 PHASE, AND IN 5
OR 4 PHASE THERE WILL BE ALOT OF WIRES CONNECTION AND
ISOLATORS USED WICH IS NOT ECONOMICAL

Is This Answer Correct ?    9 Yes 10 No

I have 4 busbar of 1000 ampere. we use 4 busbar to make 4000 ampere in one phase.my problem is that when we applied 60% load on that then busbar produced high noise.what is the reason of that and how can i minimize that noise.
