Advanced Switchgear Technology for Reliable Performance GE offers a comprehensive range of dead tank circuit breakers that support a voltage rating up to 550 kV, and are capable of carrying a continuous current up to 5,000 A. GE's circuit breakers meet or exceed the latest IEEE/ANSI and IEC standards, including C2 and M2. They can be gang operated up to 245 kV, and Independent Pole Operation (IPO) is available at all voltage levels. The DT Series from GE is characterized by advanced self-blast interrupters, leak resistant cast aluminum enclosures and durable low energy mechanisms. More than 120,000 circuit breakers with self-blast interrupters and spring-spring operated mechanism have been in service since 1989, including more than 30,000 dead tank circuit breakers. The SF6 dead tank circuit breakers assure a high level of reliability on a daily basis, even under extreme conditions such as low temperatures, highly active seismic areas, regions with high pollution levels, and a corrosive atmosphere. Utilities are heavily struggling with the decentralization of power generation and especially with the integration of renewable energy sources into the grid. Integration can conflict with existing modernization and optimization plans. Issues of reliability, safety, power quality and economics have to be taken into account when planning substations and choosing the right switchgear.
