What is SF6 vs Vacuum Circuit Breakers Analysis about?

This document compares vacuum and SF6 circuit breakers for medium voltage applications. It discusses that vacuum circuit breakers use vacuum interrupters to break currents, extinguishing the arc through metal vapor condensation. SF6 circuit breakers continue current flow through an ionized SF6 gas arc after contact separation, extinguishing the arc at current zero when heat is extracted. Self-pressuring SF6 breakers were developed to directly use arc energy to create pressure differences, eliminating auxili
