Answer / mani

I think, Max demand will always express in KVA or MVA.

and also above expression is wrong, it will be

Kw= KVA * Cos(Ø).


don't confuse others.

Answer / manoj

bill of electricity is based on Max demand (KW)and nunber
of units consumed(KWH)
Total charges= a KW + b KWh
1. KW is inversaly proportional to the Power factor
KW= KVA/power factor if power factor is low KW is high and
bill increases.

2. KWh also increases due to increase in KW.

Answer / pravin a. mhaske

Power factor affect only on kVA not KW.For e.g. Power
required to run 10kw load is same whatever the Power
factor.But for low power factor current increases & it
will affect on KVA but KW would be the same.
In energy bill KWH will be not affected but charges of
demand chrges will be increased.

Answer / ashwinmori

My question is how affect power factor on kwh and kva on
following data
Total kwh-318890
Kva-755
kw-746
kvah-320550
kvarh22820
(above reading for one month)
Above reading from Elect.Depat. Bill
Now. my question is if Power factor is 0.95 how much kwh
and kva And If Power factor is 0.99 how much kwh and kva
Please answer proper person dont misguide us.
Thanks

Answer / ultravox

Most utility companies imposed power factor penalty on
commercial & industrial customers if power factor is lower
than certain value, say 0.85. Without such penalties, the
utilities would incur higher cost in delivering power to
customers with low power factor. Active power (kW) get work
done while reactive power (kVAr) just wasted away.

Answer / ashok kumar

Actully billing depends two types
1- kva basis
2nd - kw basis
In Hariyana Billing based on KW basis
In dis m=billing there is a penalty & rebate system
If power factor is 0.9 then no panality & no rebate
if power factor below than 0.9 then panality starts 0.5 %
@.01 percent decrease of power factor
if poweer factor more than .90 then .5 % @ .01 increase of
power factor
this system is applied due to if power factor goes down
then will down but current will be higher so dat all
switchgera like poles size , conductor size, insulator
size, line loss will be much higher
thats why power factor is required upto unity
thanks this is my openion
if You know batter pl suggest

Answer / p.raju

yes i also agrre with the above..... in other words
when the power factor decreases ,in order to satisfy the
load reqirement the current drawn from the supply increases
for given voltage level..
p=VI cos(theta)
v, p are constant yes na...
now I inversly propotional to power factor..i.e the current
drawn from supply increases which leads to increase our
bill......

Answer / deepthi

cosine of angle between voltage and current..is also said to
be power factor..
decrease in power factor leads to increase in the
electricity bill..so therefore the loads having almost
nearer powerfactor to unity are more advantageous..

Answer / k.prakashchandra

pf= KW/KVA,The supplier considers only the average pf which
is 0.995(KWH/KVAH) in this case.MD is the continuous max KVA
recorded by the meter for a minimum period of 15(I am not
sure) minutes any time.KVA^2=KW^2 + KVAR^2

Answer / muhammad farooq khan

cos(phi)is a power factor. cos theta is a angle. so use
proper terms while answering to the questions. don't
misguide us.
