What is the term for the variation in the time of use of appliances that results in lower maximum demand?

The term for the variation in the time of use of appliances that results in lower maximum demand is known as load diversity. Load diversity occurs when different electrical devices are used at different times, preventing all devices from drawing their maximum power simultaneously. This variation in usage patterns helps to reduce the overall peak demand on the electrical system.

For example, if a household has several appliances that could potentially operate at the same time, such as a washing machine, dryer, and oven, load diversity means that not all of these appliances run at peak capacity at once. Instead, they are used at different times throughout the day, which leads to a lower overall maximum demand compared to a scenario where all appliances are used simultaneously.

Understanding load diversity is important in electrical engineering and management as it enables utility companies to better predict and manage energy consumption, potentially leading to more efficient operation and cost savings. Other terms like load factor, load balancing, and load distribution pertain to different aspects of electrical load management but do not specifically address the variation in time of use that characterizes load diversity.
