balanced systems

[coenst]

Why is it important to have a balanced electrical system?

 

[Mr Sworld]

I presume you are talking about three-phase electrical systems? ?:|

If so, you would like to make sure all 3 phases are balanced in terms of current demand so one phase isn't being unduely loaded.

That answer earns you Nil-pwa. ]

Having a balanced three phase load, relieves the load on the main neutral. Have a look here, http://www.aadc.ae/en/distribution%20code/%20Eng%20Rec%20No.%2010%20-%20Voltage%20Unbalance%20v1.0%20.pdf

And the answer is?

Balanced electrical system? Balanced electrical system' to me is balanced phases.

Don't leave me hangin'!

In a perfectly balanced three-phase & neutral system there will be no current flowing in the neutral. The neutral it that case,just keeps each phase & neutral @ 230 volts.

The DNO's like to keep their systems as balanced as possible, otherwise their cables neutral could get over-loaded, as it's usually the same size as one phase conductor.

If all the phase-current conductors loads flowed back thro' the neutral? Luckily it doesn't work that way.

There is also the small matter of customer`s cost. AFAIK, the 3ph meters read the highest running phase, therefore suggesting that an out-of-balance system loading will cost more to use than a well-balanced one.
