8. Diversity Factor:

The ratio of Sum of individual maximum demand and Maximum demand in power station is called Diversity Factor.

Diversity Factor= [Sum of individual maximum demand/ Maximum demand in power station]

Sum of individual maximum demand <Maximum demand in power station.
Diversity Factor> 1

9. Load Duration Curve:

In the Load Duration Curve the load elements are shown with respect to time. When the Load elements are arranged in the descending magnitude order in the Curve, thus the curve is known as Load Duration Curve.

10. Plant Use Factor:

The ratio of Station Output in KWh with respect to Plant Capacity and hours of use is called Plant Use Factor.

Plant Use Factor= [Station Output in KWh/ Plant Capacity * hours of use]

11. Node Equation:

In the electrical circuit when a junction is formed with two or more pure elements (The elements can be Resistive, Inductive, Capacitive or an ideal source of current or voltage) and are connected to each other at their terminals are called nodes. The process of calculating this nodes and check their working basis is known as node equation. In the Node Equation usually the major nodes are considered. In the nodes, where more then two pure elements are connected in a junction is known as major nodes.

In the Node Equation there are two types of admittance. They are Self Admittance and Mutual Admittance. Some times the Self Admittance is called Driving point & Mutual Admittance is called transfer admittance.
