Can someone explain the difference between diversified & unbalanced loads?
Load diversity is the comparison of individual maximum demand in a subset of a electrical distribution system, say a motor control center connected to a switchboard, to the maximum demand of the entire system, the switchboard.
Unbalanced loads draw different amounts of energy from each of the three phases A, B and C. The easiest example of an unbalanced load is a three phase panelboard with all loads attached to bus A and bus B, and nothing connected to load C.
Currents have both magnitude and phase angles. If you were to add the current vectors of an unbalanced system, the result would be non-zero. The unbalanced current would flow on the neutral conductor, where provided. In a balanced system, result of adding A, B and C currents would be zero. In reality, no systems are truly balanced, but I do make effort to keep it close.
