IEEE C37.234-2009 PDF Download

The IEEE C37.234-2009 standard provides guidance on the protection of power system buses. The standard considers various factors such as the availability and location of breakers, current transformers, and disconnectors, as well as different bus-switching scenarios. The guide discusses the impact of these factors on the selection and application of bus protection schemes.

The standard presents a range of bus protection schemes and discusses their adequacy, complexity, strengths, and limitations based on different bus arrangements. It also provides specific application guidelines for implementing these schemes. Breaker failure protection is addressed in the context of bus protection, ensuring that protection measures are in place in case of breaker failure.

Additionally, the guide addresses the need to secure bus protection schemes against corrupted relay input signals. This ensures the reliability and accuracy of the protection systems.
