An Interactive 5-Day Training Course
Advanced Circuit Breakers Operation and Maintenance
Principles of ARC Extinction and Alternatives to
SF6 Gas Circuit Breakers
Course Overview
This Advanced Circuit Breakers Operation and Maintenance training course begins with the fundamental principles of arc extinction with progression of incorporating green gas resulting in the reduction of global warming potential and reduction of carbon footprint.
Circuit breakers play an important role in the safe distribution of electrical power. The equipment needs to be operated, maintained, and installed in a safe manner securing continuity of supply to consumers. Circuit switchers have been developed to overcome some of the limitations of fusing for substation power transformers. The method or arc extinction determines the types of circuit breaker.
Hybrid circuit breakers, and state of the art high voltage circuit breakers incorporating alternatives to sulphur hexafluoride are the more efficient and safe for the environment. Higher ratings for high voltage vacuum circuit breaker are commonly installed today.
This GLOMACS training course will highlight:
- Electric power systems are designed to be as fault free as possible through appropriate network design, equipment design, proper installation, and on-going maintenance
- The Circuit breaker and its associated fault detection equipment, protective relaying, is an extremely important device, through its role of clearing short-circuit currents, disconnecting faulty elements from the power network, and thus maintaining the overall integrity of the power network
- The characteristics of hybrid high voltage circuit breaker and operations
- The introduction of new types of green gas and clean air as the state-of-the-art arc quenching medium in high voltage circuit breakers
- Minimising downtime by proper and systematic maintenance program
