Electrical load diversity factor is a ratio representing the sum of the individual maximum demands for each part or parts of the system to the maximum demand of the entire system or parts of the system. Another factor that designers consider is demand factor.Know More
Demand factor is a ratio of the sums of maximum demand on a system to the total load on the system. Sometimes designers confuse the terms "demand factor" and "diversity factor."
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. When the power is supplied by the same feeder, the demand is less than the sum of the two demands. Diversity factors have been designed for main feeders that supply power to multiple feeders which are typically 1.10 to 1.50 for lighting and 1.50 to 2.00 for power and lighting.
As an example, one can think of a feeder that supplies five users with the following load conditions: On Monday, the first person reached a maximum demand of 100 amps; on Tuesday the second user needs 95 amps; on Wednesday user three uses 85 amps; on Thursday user four needs 75 amps; and on Friday user five uses 65 amps. The feeders max demand is 250 amps. The diversity factor would be the sum of the demands divided by the maximum demand of the feeder and then multiplied by 100. In this instance 420 amps divided by 250 is 1.68 which when multiplied by 100 makes it 168%Learn more about Electricity
An inductive load pulls a large amount of current when first energized, then settles down to a full-load running current after a few seconds or cycles. When switched, inductive loads can cause excessive voltages. Some examples of inductive loads include transformers, motors and wound control gear.Full Answer >
A resistive load, or resistive load bank, is an object in which a current runs in phase with its voltage. They are commonly used as heat generators or incandescent light bulbs.Full Answer >
Electrical discrimination occurs when a protective device near a fault or short comes on and keeps the other circuits working properly. Discrimination can either partially block a fault from disrupting other systems or completely block it, depending on the type of protection device that is installed.Full Answer >
Electrical energy in the form of electricity is primarily manufactured by using massive generators equipped with turbines. It can also be generated by transforming one form of energy, which is stored in certain materials, into electrical energy.Full Answer >
