Instrument transformers are the foundation of modern electrical power systems. They provide accurate measurement, reliable protection, and safe isolation for high-voltage networks used in power generation, transmission, distribution, renewable energy, and industrial applications. Understanding their design, operation, testing, and international standards is essential for every electrical engineering professional.
This comprehensive course provides an in-depth study of IEC 61869-2, IEC 61869-3, IEC 61869-4, and IEC 61869-5, the internationally recognized standards covering Current Transformers (CTs), Inductive Voltage Transformers (VTs), Combined Instrument Transformers, and Capacitor Voltage Transformers (CVTs).
The course is designed to explain every topic in simple, practical, and easy-to-understand language, making complex IEC requirements accessible to both beginners and experienced professionals. Instead of simply reading the standard, you’ll understand the engineering concepts behind each requirement and learn how they are applied in real-world electrical systems.
