This highly participative EuroMaTech training course is designed to provide you with the skills to understand how circuit breakers are selected for specific applications, and how they are designed, installed and safely operated in industrial process plants, particularly in the oil and gas, mining and minerals processing and heavy industries.

The LV, MV and HV Circuit Breakers training course is interactive and encourages delegates to participate through questions and answers, along with opportunities to discuss with the presenter specific issues which may result in appropriate solutions.

Participants will develop following competencies by understanding:

  • Practical circuit breaker design and Operation to ensure safe and reliable application
  • The differences between circuit breakers and other circuit control and isolation devices
  • The different types of circuit breaker used for LV, MV and HV applicationsa
  • Circuit breaker operation incorporating current transformer, potential transformer and relays
  • Circuit Breaker verses current limiting fuse
  • Time current characteristics of a circuit breaker operation
  • Typical switchroom, substation and switchyard circuit breaker layouts
  • The installation, commissioning and testing of circuit breakers
  • The arc quenching methods of circuit breakers
  • The state-of-the-art hybrid circuit breakers

LV, MV and HV Circuit Breakers training course aims to enable participants to achieve the following objectives:

  • Understand the application and importance of circuit breakers
  • Learn how different types and voltages of circuit breakers operation
  • Understand the fundamental safety requirements for personnel and equipment
