TRAINING.

Overview

After participating in this course, you will be able to:

• Apply your knowledge of the fundamentals of the utility power supply system and power quality
• Recognize the important operating characteristics of major power components
• Improve substation grounding
• Discriminate between the criteria governing the application of overcurrent and overvoltage protective devices
• Implement better start-up and regular maintenance of electrical installations

Description
A properly planned and designed substation is essential for the reliable operation of a power system network. A high voltage substation comprises switching equipment, transformers, reactors, var compensators, protection, control, and automation and communication.

This course covers all aspects of high and medium-voltage substation design, including regulatory and environmental requirements, general design considerations, the application of switching and power equipment, fault calculations, safe grounding design, protection/control, automation and communication, and maintenance considerations.

Course Outline:

• Industrial and utility substation
