Microprocessor-Based Combined System Protection against Under- and Over-Voltage, Single Phase and Reversed Phasing
S.C. Kar, A.K. Mukhopadhyay · IETE Technical Review · 1986
In this paper a microprocessor-based scheme has been proposed for protecting a system simultaneously against over- and under-voltage, single phasing and reversed phasing, eliminating individual protective system for separate faults.
