The diversity factor is the ratio of the sum of the individual non-coincident _____ loads of different subdivisions of the system to the _______ demand of the complete system.

1.) Diversity factor

It is the ratio of the sum of the individual maximum demands of the various subdivisions of a system to the maximum demand of the whole system.

\(Diversity \space factor={Sum \space of\space individual\space maximum\space demand\over Maximum\space demand\space of \space system}\)

The value of the diversity factor is always greater than 1.

2.) Load factor

It is the ratio of the average demand to the maximum demand of the system.

\(Load \space factor={Average\space demand\over Maximum\space demand}\)

The value of the load factor is always less than 1.

3.) Plant capacity factor

The plant capacity factor is also known as the ratio of average demand to total plant capacity.

\(Plant \space capacity \space factor={Average\space demand\over Total\space plant\space capacity}\)

The total plant capacity is given by:

Total plant capacity = Maximum demand + Reserve capacity
