Choosing a good bus scheme is vital for operational reliability, safety and redundancy of power supply system.
Your fellow electrical engineer K. tries to discuss busbar layout and busbar schemes as per the design of a typical substation.
Introduction
Busbar(s) consist of incoming and outgoing circuits with a common point. Every circuit connected to a busbar scheme has its separate incomer, circuit breaker, isolator, potential transformer, current ratio transformer and associated switchgear. These components are arranged in a special sequence so as to trip a specific circuit in case of an abnormality.
