Answer Posted / iamdon
Inertia constant has unit of second(joule/VA).
Turboalternator has higher inertia constant in the range of
3-9 sec where as hydro alternator has inertia constant of 2
sec.
This variation is because in the case of turbo alternators
more then one(3 to 4) stages are connected to obtain high
mechanical input to alternator.Each stage has high rotating
mass.So more inertia constant.
