load factor and economic operation .
Supposing there is a group of consumers. It is known from experience that the maximum demands
of the individual consumers will not occur at one time. The ratio of the sum of the individual
maximum demands to the maximum demand of the total group is known as diversity factor. It is always
greater than unity.
High diversity factor (which is always greater than unity) is also a desirable quality. With a given
number of consumers, higher the value of diversity factor, lower will be the maximum demand on the
plant
