Training Course on IEC 62271-202: Design, Testing, Earthing

"This course contains the use of artificial intelligence."

Welcome to "IEC 62271-202: Complete Guide to Prefabricated Substations – Design, Testing & Certification."

This comprehensive course is designed to provide a practical and in-depth understanding of IEC 62271-202, the international standard governing High-Voltage/Low-Voltage Prefabricated Substations. Whether you are involved in design, manufacturing, testing, certification, installation, commissioning, or maintenance, this course will equip you with the knowledge and confidence to apply the standard in real engineering projects.

Prefabricated substations are widely used in utility power distribution systems, renewable energy plants, industrial facilities, commercial buildings, data centers, airports, hospitals, Battery Energy Storage Systems (BESS), EV charging infrastructure, and smart grid applications. Their compact design, factory assembly, and reduced installation time make them an essential solution for modern electrical power systems.

However, designing and deploying a prefabricated substation requires much more than selecting a transformer and switchgear. Engineers must ensure compliance with international safety and performance requirements related to electrical ratings, earthing, insulation, enclosure protection, mechanical strength, environmental performance, internal arc protection, and product testing.

This course explains these requirements in a clear, practical, and structured manner. Instead of simply reading the clauses of the standard, you will understand the engineering principles behind them and learn how they are applied in industry.

In this course, you will learn:

• The scope, terminology, and structure of IEC 62271-202

• Design and construction requirements for prefabricated substations

• Electrical ratings, service conditions, and enclosure classifications

• Earthing systems, equipotential bonding, and personnel protection

• Enclosure design, ventilation, fire behaviour, and environmental protection

• Internal Arc Classification (IAC-A, IAC-B, and IAC-AB) and assessment criteria

• Type tests, routine tests, and acceptance requirements

• Dielectric testing, temperature-rise testing, short-time withstand current testing, and mechanical verification

• Sound level testing, mechanical impact testing, and solar radiation testing

• Power transformer rating and derating inside prefabricated substations

• Material selection, corrosion protection, coatings, and concrete characteristics

• Installation, commissioning, operation, and preventive maintenance

• Information required for enquiries, tenders, procurement, and product certification

• Practical guidance from the informative annexes, including earthing arrangements, enclosure materials, solar radiation effects, and electronic equipment installation

Throughout the course, complex technical concepts are explained using practical engineering examples, diagrams, flowcharts, and real-world applications, making the standard easier to understand and apply.

Who should take this course?

This course is ideal for:

• Electrical Design Engineers

• Power System Engineers

• Testing and Certification Engineers

• Commissioning and Maintenance Engineers

• Utility and Renewable Energy Professionals

• Manufacturers of Transformers and Switchgear

• Consultants and EPC Engineers

• Quality and Compliance Engineers

• Engineering Students and Graduate Engineers

• Professionals working in NABL, IEC, or ISO/IEC 17025 accredited laboratories

No prior knowledge of IEC 62271-202 is required. The course begins with the fundamentals and gradually progresses to advanced engineering topics.

By the end of this course, you will have a strong understanding of IEC 62271-202 and the ability to confidently apply its requirements when designing, testing, specifying, evaluating, and commissioning prefabricated substations.

Whether your goal is to enhance your professional skills, support product certification, improve testing knowledge, or strengthen your expertise in modern power distribution systems, this course will serve as a valuable technical resource throughout your engineering career.
