Switchgear design, development and service
This chapter describes the design, development and operation of SF6 switchgear [1-16]. It also describes how the development of generation and transmission has influenced switchgear evolution (see Appendices A and B). Factors that have contributed to the simplicity of design and increased the reliability of SF6 switchgear are addressed and the important features of various manufacturers, designs in first-, second- and third-generation interrupters and improvements in circuit breaker performance are highlighted. It also addresses issues associated with installation and on-site operations and monitoring.
