A balanced three phase load is where the current flowing in all three phases of the load are reasonably close to each other.
Another answer
When the voltage and measured current draw do not deviate by more than 2 percent under load.
AnswerA balanced three-phase load is one in which each of the three loads is identical in all respects (magnitude and phase). Further to the first answer, the three line currents must not all be 'reasonably close', they must be identical -i.e. the same value and phase relationship.

∙ 9y agoIt is a load on a three-phase system that produces unequal load currents in the three phases. The ideal load is always balanced, with equal currents in the 3 live wires.
In LV power distribution it is usually not possible to guarantee a balanced load except by aggregating up a lot of loads and hoping that the total load is reasonably balanced. Thus a street of houses will usually provide a reasonably balanced load on the three-phase supply even though each house is connected to only one phase.

What is the effect of an unbalanced load of generators?
An unbalanced load prevents the generator delivering its maximum power. That is because each phase has an equal upper current limit that it can deliver, and in an unbalanced system, if one phase is delivering the rated current it follows that the others are not.
Line read 20 amp different per phase to load?
The electrical term for this condition is called an unbalanced load.
What is difference between balanced and unbalanced load?
three phase load is said to be balanced when the impedance and power factor of each load is equal.in this condition phasor sum of currents and phase voltages add up to zero.
How much will neutral current be in a 3phase 4-wire y system with a balanced load?
Balanced load means no unbalanced currents, so the neutral current should be near zero.
Is the line is necessary for the balanced star- connected load?
I think you probably mean is a neutral conductor necessary for a balanced star-connected load? If this is what you mean, then the answer is no, it isn't, as the phasor-sum of the phase currents will equal zero. Often, though, it is difficult to achieve a balanced load, so a neutral is then necessary, as it is needed to provide a return path for the unbalanced current -without this neutral, the phase voltages would change and become unbalanced.
When was Unbalanced Load created?
Unbalanced Load was created on 2009-08-04.
What is a neutral wires' function?
To carry the unbalanced load current.
What is the effect of an unbalanced load of generators?

Does the change in the load resistor change the current in the arms of an unbalanced bridge?
No
What happened when one phase missing of a 3 phase load?
If one phase really is missing, then you have an unbalanced load.
What significance has a power factor in an unbalanced system?
A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
Line read 20 amp different per phase to load?
The electrical term for this condition is called an unbalanced load.
How do you balance the unbalanced load in 3 phase?
If the load is connected in wye (star) and it has a neutral, then the vectorial-difference of the phase currents will flow in the neutral and there will be no problem. On the other hand, if there is no neutral, then an unbalanced load would cause unbalanced phase voltages.
What are the Effects of unbalance loading on kWh meter?
You are, presumably, talking about an unbalanced three-phase load. The answer is no, because the wattmeter takes unbalanced loads into account.
How do you get line to neutral voltage form line to line voltage especially when there is unbalance in line to line voltage?
It is highly unusual for the supply system's line voltages to be unbalanced as the source is considered to be an infinite bus. On the other hand, it is not in the least unusual for the line currents to be unbalanced, as they are determined by the load. If a unbalanced star (wye) connected load has no neutral, then the phase voltages will become unbalanced.
What is the difference between Kilowatt Meter with balanced load and with unbalanced load?
'Balanced loads' apply to three-phase a.c. loads. A three-phase kilowatt hour meter will measure both balanced and unbalanced loads, when correctly connected.
How do you use cumbersome as a verb?
"The load was CUMBERSOME on the small cart" Like being ungainly, unbalanced.
