The objective of this module is to review the different bus layouts that are used in power systems and to present the different protection schemes that are installed to protect against bus faults. After study of this course and the associated workbook the participant should be able to understand the following overall concepts and apply them to his/her day-to-day work activities. He/she will also be able to answer related test questions on these subjects: Features of different bus arrangements, Single breaker - single bus, Single buses connected with bus tie breaker, Main and transfer buses with single breaker, Single breaker - double bus, Double breaker - double bus, Ring bus, Breaker-and-a-half bus, Special problems of bus protection, The ground fault bus, Partial differential protection with overcurrent relays, Directional comparison schemes, Residual current differential schemes, CT saturation problems, Multi-restraint relays, Linear coupler, High impedance relays.
If you are taking this course for NERC credit, the following credits will be reported.

- Trainees will be able to describe different bus arrangements used on power systems, and be able to explain the advantages and disadvantages of each.
- Trainees will be able to describe simpler forms of bus protection, of the type that would typically be used on a distribution substation.
- Trainees will be able to describe some of the problems that are particular to bus protection, including the wide divergence of current flows in different circuits with the resultant problems of CT accuracy.
- Trainees will be able to explain the need for high speed differential protection if a given bus is a strategic part of the power system.
- Trainees will be able to explain the problem associated with CT saturation and the need for multiple restraint coils on differential relays.
- Trainees will be able to describe what distinguishes a linear coupler from a normal CT and explain how linear couplers are used in protection schemes.
- Trainees will be able to describe the operation of high impedance differential relays.
