Which of the following expressions clearly indicates determination of the diversity factor in a power system?

Important terms related to power generation

\(1.) Diversity \space factor = \rm \frac{Sum\ of\ Individual\ maximum\ demand} {Maximum\ demand\ of\ the\ whole\ system} \)

The value of the diversity factor is always greater than 1.

\(2.) Average\space demand={Total\space energy\over Total \space time \space in \space hrs}\)

\(3.) Load\space factor={Average\space demand\over Maximum\space demand}\)

\(4.) Demand\space factor={Maximum\space demand\over Connected\space load}\)

\(5.) Plant\space capacity \space factor={Average\space demand\over Plant\space capacity}\)

\(6.) Utilisation \space factor={Maximum\space demand\over Plant\space capacity}\)

All the above factors always have value less than 1.
