    Do a Power Transformer is operated at full load condition only and is disconnected under light load condition ??

    A transformer can be disconnected loaded or unloaded. Makes no difference.

    yes, you can vary load from 0 to 100% without problem. Usually they are not operating at full load.

    It depends on how the load varies, and the voltage drop along the way to consumers.

    Typically, it will be a load tap changing transformer (LTC) that will keep the voltage amid nominal limits due to utility politics.
