About Course

This comprehensive course offers in-depth training in the principles and practical applications of electrical design for substations and building services. It covers the key components of electrical systems, design standards, protection schemes, and equipment selection. Participants will learn to develop safe, efficient, and code-compliant electrical layouts tailored for both utility substations and commercial/residential buildings.

The course combines theoretical knowledge with real-world design practices, including the use of modern software tools for drafting and simulations. It is ideal for electrical engineers, technicians, consultants, and anyone involved in power system design, building services, or infrastructure development.
