what is mean by ideal infinite bus? why it is required to
consider in fault short circuit calculations?

Answer Posted / Surbhi

An Ideal Infinite Bus (IIB) is an imaginary electrical network element with zero impedance and unlimited current capacity. It is used as a reference point in power system analysis, such as short-circuit calculations. The IIB allows engineers to simplify complex electrical networks by replacing sections of the network with a single node, reducing the complexity of calculations while maintaining accuracy.
