Transformer Protection Tutorial Series #1

Series #1: Transformer Protection - From Theory to Configuration and Testing

For beginners and experts in Transformer Protection. This webinar series is designed for engineers, consultants, planners, and operators in utilities, industry, and infrastructure. It provides comprehensive coverage, including theory, device selection, configuration, and testing.

What it's all about

In our transformer protection webinar series, you'll gain comprehensive knowledge about key protection functions, typical transformer protection applications, and how to configure a SIPROTEC 7UT8x using DIGSI 5. Additionally, you'll learn to perform testing with the SIPROTEC 5 DigitalTwin and an OMICRON test device.

Discover the essentials of transformer protection, structured into two focused blocks:

Series #1: From Theory and Product Overview to Configuration and Testing
Dive into transformer protection principles and explore the general theory. Learn how to configure modern differential protection using DIGSI and perform thorough testing.

Series #2: Applications and Functions
Explore advanced applications for 3-winding transformers, restricted earth fault protection, auto-, special-, and phase-shift transformers.
