📅 Live Training: 08.02.2026
🕑 Time : 2:00 PM – 5:00 PM 💬 Weekly Wednesday Evening Q&A
Course Summary
Learn how to accurately calculate the size of CT/VT using industry standards and best practices. From understanding transformer ratings to selecting appropriate burdens, this course will equip you with the knowledge and skills to confidently size CT/VT for various electrical systems. Current Transformers (CTs) and Voltage Transformers (VTs/PTs) are the foundation of metering and protection systems in power networks. Incorrect CT/VT sizing leads to measurement errors, protection maloperation, saturation issues, and system instability. This course teaches you how to size and select CTs and VTs correctly, using practical calculations and real power system design scenarios.
