How to calculate power Consumsition for Electricity

I think that power consumption for electricity means electric charges. So I'll answer u as below:_

Depending on your load power and how long you have to use these loads.

Example: You use 2kW electric kettle for 3 hours.

Your power consumption for electricity is:

kWH = 2kW x 3 Hrs

=6 kWH

1 kWH = 1 unit

I don't know how much you have to pay for 1 unit of electrical charges in Malaysia.

But,we calculated above 6 kWH consumption also means for 6 units.

You can calculate for other loads as shown above. And then u make summary for all loads to be used.

Finally, you can calculate for electrical charges: total units x Rate of Electric charge(RM) per unit.

I read the query. The power calculation I mean is right from the basic. Here the multiplication of Rate is at final stage.

The Energy consumed is V * I * (power factor) * time in Hrs.

This is known as Watt.Hour . If devided by 1000 it is KWH. The PF (power factor) is important. In case of polluted loads the energy calculation differes. If you need further details conact me on my mail chetan@inventaelectro.com

thank you for you for your information.

rite now i want to calculate our electricity consumstion for our plant...

for example i have some information for you

I=1400 A

V=415

pf =0.75

and H=20 hrs

but our meter for electricity consumtion shows about 19579 Kwh

if you dont mind, does any factor will be effect our calculation for this matter.

i hope you can help me

thank tou

if you use a 3 phase current then

you have 415. 1400. 0.75 . 1.732=754719/1000=754.7 kw .20h=15094kWh

From what you are describing, I suggest you investigate the following:

The value for current is too low (you are using more that the 1400A you stated)

The pf of 75% (0.75) is stated too low, and should really be a higher number.

If the incoming feeder cables and transformer is sized for 1400A and you're drawing more power, you may need to negotiate for a larger service connection.

If these suggestions lead to a solution let us know. If not, let us know and someone will come up with a better idea.

Good luck!

Just like you do anywhere else Malaysia or BumFuck Egypt, the electrons don't care.

Dear Sir,

For the power calculation in Malayasia, better one will have to approach the nearest Malayasian Sub Division from where one is drawing the electrical power.

On contacting the right authority , over there , the concerned will be in a position to solve the querries related to Electrical Power.

Otherwise for single phase power supply it is E x I x P.F. x Hrs and for 3 phase it will be v- 3 E I P.F. x Hrs will be the electrical energy consumed in Watt Hours and divided by 1000 it will be KWH.
