The fundamental concepts of bus bar protection will be discussed in this series of session. In this series we will discuss about the basic concepts of Bus Bar Protection. Difference Between High Impedance and Low Impedance Bus Bar Differential Protection. The concept of CT saturation and its effect on the performance of Bus Bar Differential Protection. High impedance bus bar differential protection calculations. Centralized and Decentralized bus bar protection schemes. Concepts of Bus Zone and Check Zone in case of bus bar differential protection schemes. At the end of this series you will learn all the fundamental concepts related with bus bar differential protection. All the sessions will be in Hindi as well as English and you may watch these sessions as per your convenience.
For better understanding of the concepts explained in this session, it is desirable that following sessions must be watched:
1. Bus Bar Protection | Concepts and Applications of High Impedance Bus Bar Differential Protection |

Done

[@AmirKhan-jt5bd]

For tripping we need 2 out 2 for reliability but you missed the part when main zone or check zone is out of service and also if ct supervision is unhealthy in main zone or check zone.
