| چکیده | ||
| The design and application of a fuzzy logic based controller to a leakage current relay was presented in this paper. A novel approach based on fuzzy logic to form the tripping action of leakage current relay was investigated. In addition to the theoretical aspect of fuzzy logic, detection of a leakage current, measurement of the leakage current, determination of its duration, trip opening of faulty cases and detailed system architecture were also introduced. The inspected fuzzy logic technique to control the tripping action of the leakage current relay was intended to improve the performance of conventional leakage current relay control for human safety and system reliability. The relationship between the controlled output of the fuzzy processor and properties of leakage current for the proposed relay was explored by using a graphical output expression. It was observed that the proposed leakage current relay based on fuzzy logic was more reliable than conventional leakage current relay. | ||
