Answer Posted / bharat rathod
> Y-bus and Z-bus both are used for designing and modeling of transmission system.
> Removal of short-circuit element is easy in case of Z-bus. And any modification in Z-bus is easy. Z-bus is always full matrix.
> Any modification like removal of any transmission line is difficult in case of Y-bus. And, Y-bus is highly sparse. Y-bus is having 97% sparcity.
