Question { 10483 }
what is VFD and how to save the power by using VFD?
Answer
vsd,inverter,vsvf drive means it is a electronics device
based on volt/hz ratio.
f=N*p/120 means if u will varry the frequency the rpm will
also varry. thus P= 1.73*VI COS PHI IF THE device getting
less current the power also dawn and unit also decrease
hence the power will save

How I design capacitor bank for different load.7MW
connected load.
Answer
(kva) but exectly we must know the desired powerr factor
KVAR = kw/Sin theta
pf= cos theta= desired pf
let 0.99 we require than cos Q = 0.96
Q= Cos inv 0.96
SinQ Will = sin * Q
Kvar = Sin Q* Load
| Is This Answer Correct ? | 1 Yes | 4 No |
Question { 6248 }
its Kva and Kv are same?
Answer
Kilo volt means the potential difference measured between
two points. Kilo volt ampere is the actual power consumed
by the electrical load.this is apparent power and vectorial
sum of kw and kvar
