Electrical Power Substation: Maintenance, Design, Testing, Grounding and Safety Course

Course Overview:

The course covers the concepts of designing, installing and maintaining HV/MV substations.

It deals with the substation components, overcurrent and earth fault protection system components, and also performs grounding and fault calculations. This niche also deals with switchgear varieties, and relay mounting, as well as other aspects of commissioning and testing. 

The practical focus will offer the participants substation operations while assuring reliability, safety and efficiency.

This course is for engineers, supervisors and utilities to manage substations and their equipment and projects.

Course Objectives:

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

• Design, install, commission, test, operate, control, and maintain HV/MV substations in a professional manner
• Identify the various types of substations covering its parts, equipment, and major components
• Recognize over current protection for phase and earth faults as well as the recommended grading intervals
• Employ proper commissioning covering pre and cold commissioning, start-up, hot commissioning, the start of production, performance test, and acceptance of plant
• Perform testing procedures and basic calculations
• Illustrate medium voltage switchgear and oil circuit breakers
