While designing modern power systems, it is aimed to keep the cost items first and then the malfunctions that may occur on the relevant system at minimum levels. There are overhead lines with radial and individual outlets among the distribution networks built. About lines, frequent breakdowns occur due to bird strikes, insulator breakdowns, humidity, etc. In this study, it is aimed to examine the effects of faults experienced at different points of a power system and to dampen these faults with the designed controlled breaker without affecting different points of the system. In the study, it was observed that the rated current, which was at the level of 54 A, increased to 1.5 kA with the fault. The application is of great importance in terms of increasing equipment life in transmission and distribution networks and isolating fault zones for only 0.001 seconds in a power system with more than one supply point.
