Training Overview

Training Overview

Circuit breakers are crucial components in every electrical installation, serving as the primary protection for both equipment and operators.

This LV and HV Circuit Breakers training course offers a comprehensive overview of the essential knowledge required for both low voltage and high voltage circuit breakers. The course emphasizes the construction, operation, arc-quenching methods, maintenance, and testing of various circuit breaker types. Circuit breakers are categorized based on their arc-extinguishing techniques. This training will cover the different types, including oil, air, gas, and vacuum circuit breakers. Additionally, the course focuses on effective maintenance strategies tailored to each circuit breaker type, ensuring reliability and protection through condition-based maintenance in accordance with IEC standards.

This LV and HV Circuit Breakers training course will feature:

  • Understanding the types of circuit breakers
  • Operation of the components of the circuit breakers
  • Types of arc quenching methods in circuit breakers
  • Testing of circuit breakers
  • Maintenance of circuit breakers

What are the goals?

By the end of this training course, participants will be able to:

  • Understand the role and importance of circuit breakers
  • Determine the components and operations of circuit breakers
  • Explain the different types of maintenance and testing for circuit breakers
  • Care and monitoring of SF6 circuit breakers
  • Comprehend the importance of the efficient operation of circuit breakers

Who is this Training Course for?

This LV and HV Circuit Breakers training course is suitable to a wide range of technical professionals but will greatly benefit:

  • Operations & maintenance engineers, supervisors & technicians
  • Maintenance technicians
  • Electrical Support Engineer- Maintenance Operations
