The Scandinavian Academy for Training and Development employs modern methods in training and skills development, enhancing the efficiency of human resource development. We follow these practices:

• Theoretical Lectures: 
  • We deliver knowledge through advanced presentations such as PowerPoint and visual materials, including videos and short films.
• Scientific Assessment:
  • We evaluate trainees skills before and after the course to ensure their progress.
• Brainstorming and Interaction: 
  • We encourage active participation through brainstorming sessions and applying concepts through role play.
• Practical Cases:
  • We provide practical cases that align with the scientific content and the participants specific needs.
• Examinations: 
  • Tests are conducted at the end of the program to assess knowledge retention.
• Educational Materials:
  • We provide both printed and digital scientific and practical materials to participants.
• Attendance and Final Result Reports:
  • We prepare detailed attendance reports for participants and offer a comprehensive program evaluation.
• Professionals and Experts: 
  • The programs scientific content is prepared by the best professors and trainers in various fields.
• Professional Completion Certificate: 
  • Participants receive a professional completion certificate issued by the Scandinavian Academy for Training and Development in the Kingdom of Sweden, with the option for international authentication.
• Program Timings:
  • Training programs are held from 10:00 AM to 2:00 PM and include coffee break sessions during lectures.

Why Choose this Course?

This course will provide delegates a solid understanding on the safe use of circuit breakers, switchgears and associated equipment that requires correct initial selection, operation and maintenance. Strong emphasis on detailed understanding of how these devices should be installed, the local substation and system ratings, and how the various breakers operate; in order to enable accurate troubleshooting and subsequent repair.

On completion, delegates will be equipped or will have enhanced skills to ensure that circuit breakers and switchgear are installed, operated safely and maintained in a fashion that ensures safe and stable operation. Delegates will be exposed to recognize faults and ensure the underlying causes are identified to reduce possible further failures.

This course will feature:

• Understanding the types and functions of circuit breakers
• Operation principle of medium voltage circuit breakers
• Identification of testing equipment and instruments
• Interpretation of single line drawings
• Troubleshooting and maintenance of switchgears
