Pu stands for per unit and this will be used in power
system single line diagram there it is like a huge
electrical circuit with no of componenets (generators,
transformers, loads) with different ratings (in MVA and
KV). To bring all the ratings into common platform we use
pu concept in which, in general largest MVA and KV ratings
of the component is considered as base values, then all
other component ratings will get back into this basis.Those
values are called as pu values.
