Experimental Validation of Transformer Protection Numerical Relay

Abstract

The importance of testing and validation in power systems guarantees the reliability and the accuracy of the important components like numerical relays. The project focuses on testing and validating the performance of the MiCOM P642 relay, which is part of the important components in a power system protection application. In carrying out practical testing in the assessment of performance under varying fault conditions, the use of advanced tools with capabilities like the computer-Monitored Control (CMC) injection kit and Test Universe software is imperative. The theoretical calculation is used as a benchmark in the determination of real performance, while optimization of setting in the Programmable Scheme Logic tab enhances the overall performance. In developing a comprehensive manual as a learning resource to avail step-by-step procedures and practical guides for relay testing, everyone will be exposed to knowledge and skills on how this can be accomplished. We do this with a view to contribute and support the advancement of electrical protection technology to ensure transformer numerical relay reliability and accuracy, such as MiCOM P642, and to guarantee safe, stable, and reliable operation of the power system for the benefit of the society.  The features of this project are to present a demonstration of the importance of proper testing and optimized settings to maintain the safety and reliability of the power system, showing how transformer numerical relays work in general.
