When number of alternators are interconnected forming a system which may be treated as an infinite bus. Infinite bus bar is one which keeps constant voltage and frequency although the load varies. Thus it may behave like a voltage source with zero internal impedance and infinite rotational inertia

Can you any one explain different between instantaneous over current and IDMT
