| Abstract: | This paper presents the improved algorithms and the protection system of a power transformer differential protection implemented by a microcomputer. In order to detect and distinguish the trans- former inrush, a comprehensive optimized digital filter with high precision is designed. Several ways for increasing the sensitivity and reducing the calculation work of the system are developed. Satisfactory results are obtained by simulation tests on a micro -computer. |
