What is the diversity factor in a power system?
The ratio of the sum of individual maximum demands of all consumers to the maximum demand of the power station
The ratio of maximum demand of the power station to the sum of individual maximum demands of all consumers connected to it
The ratio of the maximum demand of the power station to the sum of individual minimum demands of all consumers
The ratio of the maximum demand of the power station to the sum of average demands of all consumers connected to it
The ratio of the sum of individual maximum demands of all consumers to the maximum demand of the power station
The diversity factor is defined as the ratio of the sum of individual maximum demands of all consumers to the maximum demand of the entire power station. It represents the extent to which the maximum demands of various consumers do not occur simultaneously.
IEEE Std 141 (Red Book)
The diversity factor is defined as the ratio of the sum of individual maximum demands of all consumers to the maximum demand of the entire power station. It represents the extent to which the maximum demands of various consumers do not occur simultaneously.

In a power system, individual consumers have different peak demand times based on their usage patterns. Because these peaks rarely coincide, the system's total peak (maximum demand of the station) is typically lower than the mathematical sum of individual peaks. The diversity factor accounts for this non-coincidence, allowing utility companies to design infrastructure for a capacity lower than the simple sum of all consumer loads.
Diversity factor is always greater than or equal to 1.
Higher diversity factor indicates that loads are occurring at different times, which reduces the required installed capacity of the system.
It is a key parameter in determining the economics and capacity planning of distribution networks.
Reduces the cost of power system infrastructure by allowing for a lower total capacity.
Optimizes the utilization of transmission and distribution assets.
Complexity in predicting actual simultaneous peak demand for new residential/commercial areas.
Can lead to system overloading if consumer behavior patterns change significantly.
Load forecasting for transmission and distribution planning.
Determining the required capacity of transformers and substations.
Diversity factor values typically range between 1.2 and 2.5 depending on consumer type (residential, commercial, or industrial).
Option B represents the reciprocal of the diversity factor, often related to the coincidence factor or load diversity.
A is correct тАФ The diversity factor is mathematically defined as the ratio of the sum of individual maximum demands to the station's simultaneous maximum demand.
Remember that Diversity Factor is always тЙе1, whereas Coincidence Factor (or Load Diversity) is always тЙд1 as it is the inverse of the diversity factor.
