    why the value of demand factor and load factor are always less than 1 ???

    If the power factor is perfect, it will be 1. That's tough to get with anything other than than a purely resistive load.

    The more inductive or capacitive a load is, the further away from 1 you get.

    load factor is the average power divided by the peak power, over a period of time.
    Since peak power is always higher than or equal to average power then the load factor can never be greater than 1.

    Demand Factor is the ratio of (a) the maximum real power consumed by a system to (b) the maximum real power that would be consumed if the entire load connected to the system were to be activated at the same time.
    since total connected load power is always higher than or equal to consumed power. then the demand factor can never be greater than 1.
