Course Catalogue.

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

• Analyze substation performance and power quality issues to improve system reliability and operational efficiency
• Evaluate high‑ and medium‑voltage substation components to identify technical risks and performance limitations
• Design and assess substation grounding systems that meet safety, stability, and regulatory requirements
• Select and apply appropriate overcurrent and overvoltage protection strategies for HV/MV installations
• Plan and manage testing, commissioning, and maintenance activities to support long‑term asset integrity

Description

Designing, operating, and maintaining high‑ and medium‑voltage substations requires more than technical knowledge—it demands sound engineering judgment in environments shaped by safety risk, regulatory requirements, and system reliability expectations. Decisions related to equipment selection, grounding, protection, and maintenance directly impact operational continuity and public safety.

This course focuses on the practical considerations engineers and technical professionals face when working with HV/MV substations. You will examine how switching equipment, transformers, reactors, grounding systems, and protection schemes function together within a substation, and how design and operational decisions influence system performance. Emphasis is placed on applying regulatory requirements, performing fault calculations, and integrating modern protection, control, and communication systems.

Through a structured, application‑focused approach, this course equips you with the tools and frameworks needed to make informed design, testing, and maintenance decisions. You will leave better prepared to manage substation systems confidently, reduce risk, and support reliable power delivery in real‑world operating environments.
