i dont understand the phase balance in power in our houses?

Question

ina house if there r 3 flore how in each phase the power is balanced???

Answer 1

phase balancing is the job of the power distribution utility / agency
in case of household power
assuming that each of 3 floor is supplied by the 3 differnt phases, which is standard practice, power in the 3 phases can never be balanced. each household has typical & varying power needs

the power utility or agent checks the output of his transformer and studies the loading of the 3 phases over a period of time.
a few households or groups may be targetted & supplied with a different phase, for balancing purposes
> from max. loaded phase to min. loaded phase

Answer 2

Wiring should be done Load should be distributed equally in all the three phases,.Just I am giving example, In three floor 6 A/C 3 geycers,3 cooking range 30 lights 30 power sockets.ie means each phase 2 A/C 1 geycer ,1cooking range, 10 lights 10 power socket to be equally sharing the load in one phase .Current load should be kept same in all individual phases.If your power supply is 3 phase 150Amps individual phase also equally loaded.If it maintained your neutral current will be negligible if all the phases are balanced.Distribution board also designed wiring should be made accordingly by electrical people.I hope I covered your doubt

Answer 3

One phase per floor? Are you people serious?

I don't know anyone who has 3-phase power in their home. The only need for a 3-phase connection exists in industry.

Power to your home is supplied as a single 240V phase, which is divided into two legs of 120V each. Most circuits use only one of these legs (outlets and lights). Some use both (dryer, stove, hot water tank). 240V circuits are 'automatically' balanced because they use both legs, without passing return current on the neutral wire. 120V circuits, however, require a neutral wire for this return current. Because of this, you will have as much current on the neutral bus as you do on BOTH legs of your line, so neutrals must be sized accordingly.

In addition, it's best to 'balance' the legs by placing approximately equal loads on each one. This keeps the current draw on each leg to a minimum, which reduces heating and increases safety.

Answer 4

It really does not matter if the phase balances in a home or a building. Allowing all phases to operate normally during an imbalance condition is one job of the neutral wire. It may become a problem in large factories using megawatts but can be controlled by proper local distribution.

Answer 5

they are not completely balanced they try to make it near balanced to have maximum efficiency.they calculate all the loads
make three regions nearly equal in their consumptions.you can go and check all the equipments used power and understand how they balance it.

Answer 6

If your spelling and grammar are indicative of your intellect, it is best that you leave electricity alone.
