Introduction

This module will discuss the medium voltage switchgear assembly: what it is, how it is used, what its components are, and how it interfaces with a medium voltage circuit breaker.

When we say “medium voltage,” we are referring to a range of 1000 volts to 38 kV. This is the voltage range discussed in Module 6, Medium Voltage Power Circuit Breakers.

Module 6 discussed two Circuit Breaker technologies: Vacuum Interrupter and SF6. The emphasis was on vacuum. Likewise, this module will emphasize vacuum switchgear assemblies. This is the worldwide application trend for medium voltage assemblies.
