Question
`Why dose voltage rated at 11kva`
Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By

# 1
Most of the voltages in the power system are rated at
11kv,132kv or likewise.It is observed that these voltages
are a multiple of 11.This is because of the form factor
which is equal to 1.1 in the equation for the emf generated
by the alternator.Since the form factor is a multiple of 11
most of the voltages assume forms like 11kv,132kv or 220kv.

 Is This Answer Correct ? 1 Yes 1 No
