differenve between frequency management and channel assignement
A balanced bridge has zero volts across the two test nodes, while an unbalanced bridge has non zero volts.
'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.
For a balanced three-phase load, the neutral current is zero, so the loss of the neutral would have no effect.However, for an unbalanced load, the 'difference' between the line currents results in a neutral current.So, for an unbalanced load, if no neutral current can flow, then the load's neutral point will no longer remain symmetrical, and the line voltages will become unbalanced. If the unbalance is severe, then individual loads may be subject to over-voltages or under-voltages.
