  • Abstract
    The authors describe the design, implementation and testing of a microprocessor-based relay for protecting single-phase and three-phase transformers. The relay implements algorithms that use nonlinear models of transformers to detect winding faults. The algorithms, hardware and software are also briefly described. The performance of the relay is checked in the laboratory. The testing procedure and some test results are also presented
