| 520 | _aThis thesis presents an integrated, economical, actual, and industrial multifunction digital relay MDR1 to be used in the protection of three phase induction motor. Possible faults are studied with their causes. Recommended protective functions are presented and implemented using micro - controller 8951. Flowcharts for each routine for each function are implemented with corresponding software programs. Nine functions were designed and implemented inside the relay MDR1 and these functions are protection against over and under current, over and under voltage, unbalanced currents and voltages, over temperature of windings, and earth fault protection | ||
