Answer / vinay vishwakarma

When the first electric battery or generation came that was 1.1 v and then all the generation of electricity has a multiple of 1.1 V which is also known as Form factor. That is why 11 KV is generated in power station and machine also become big. i.e. why it is simple and reliable supply for power system.

what happen if generator of micro hydro running at only a small percentage of its capacity, as a comparison, if the diesel generator that runs on only a fraction of its capacity there will be a wet stacking
