Definition diversity factor electrical. Diversity factor is defined as the ratio of the sum of the maximum demands of the various part of a system to the coincident maximum demand of the whole system. In electrical design diversity factor can be described by considering two buildings which have the same maximum demand but the demand is needed at different intervals of time. We can understand better if we give a practical example of diversity factor. Diversity factor definition is the ratio of the sum of the maximum power demands of the subdivisions of any electric power system to the maximum demand of the whole system measured at the point of supply.
In other words we do not use all the loads at once at home i e. We define the diversity factor of an electrical system as the ratio of the sum of maximum demands of individual loads connected to the system to the simultaneous maximum demand of the system itself. In the context of electricity the diversity factor or simultaneity factor is the ratio of the sum of the individual non coincident maximum loads of various subdivisions of the system to the maximum demand of the complete system. Diversity factor should not be confused with diverseness or diversity which refers to the percentage of time that a single grid component operates at peak loading.
Higher the values of load factor and diversity factors lower will be the overall cost per unit generated. Diversity factor nbc type of load type of building individual house hold individual dwelling of a block small shops stores offices business premises small hotels boarding houses etc lighting 66 of total current demand 90 of total current demand 75 of total current demand heating and power 100 of total current demand. Thus there is a diversity in the occurrence of the load. Here the term diversity factor comes into the picture.
The residential load has the highest diversity factor. Significance of load factor and diversity factor. The diversity factor is always greater than 1. In the same manner it is possible to compute the diversity factor on a substation a transmission line or a whole utility system.
When the power is supplied by the same feeder the demand is less than the sum of the two demands. The maximum demands of the individual consumers of a group do not occur simultaneously. Load factor and diversity factor play an important part in the cost of the supply of electrical energy. The diversity factor of a feeder would be the sum of the maximum demands of the individual consumers divided by the maximum demand of the feeder.
The capital cost of the power station depends upon the capacity of the power station. What is diversity factor in electrical wiring installation.
