Lecture series #5 on protection topics with Prof. Dr. Lemmer

Lecture series #5 targets on medium voltage topics focused on breaker failure protection, transient overreach, supervision functions, and also residual compensation factors.

This webinar series is designed for professionals working in the field of protection, where a solid understanding of relay protection is crucial.

What it's all about

Enhance your knowledge and skills in operating and maintaining relay protection systems for distribution and transmission grids. This supplementary lecture series expands upon the foundational webinar

Series #1 titled Basics in Protection.
Series #2 targets specific distribution and transmission topics
Series #3 targets on Distance Protection on short lines and cables, Reverse Interlocking, and Auto Reclose Schemes
Series #4 targets on high voltage topics focused on teleprotection, weak infeed and application schemes in distance protection

In this series we focus on the topics below.

Learn from Prof. Dr. Lemmer, a protection specialist and for many years and connect with Jackson da Silva, an experienced trainer for protection systems in the Power Academy.
