Differential Protection is one of the most important protections for Transformers, reactors, and Bus Bar. In this video we will discuss about the testing of numerical differential protection relays using Omicron Relay Test Kit. All the concepts required for testing of differential protection will be explained in detail. This session focusses on the following aspects of differential relay testing:

1. Differential Stability Test.
2. Differential Pickup Test
3. Differential Relay Slope Test.
4. Second Harmonics Blocking.
5. Fifth Harmonics Blocking.

An incredible amount of time and effort is needed to develop high-quality video tutorials. Each video takes approximately 6-8 hours to complete which includes learning the concept myself, brainstorming creative ways to teach and explain the concepts, creating the presentations (if delivered through PPT mode), Setup of analysis software, video recording, and editing. Your support truly makes all the difference. So, please like👍🏻, comment and share this video with your friends and keep watching this channel for more such videos in future.
