The application of time-graded protection to radial feeders, parallel feeders, and ring main system will be discussed here: Application # 1. Protection of Radial Feeders: The main characteristic of a radial system is that power can flow in one direction only, from generator or supply end to the load end. It has the drawback that continuity of supply cannot be [...]

In this article we will discuss about:- 1. Introduction to Carrier-Current Protection 2. Methods of Carrier-Current Protection 3. Advantages. Introduction to Carrier-Current Protection: In modern high-power electrical systems it is necessary to have quick-acting protections on long transmission lines. The requirements to be met by such protections are fully satisfied by the circulating current differential protection with its high sensitivity, [...]
