Microcontroller based overcurrent relay and directional overcurrent relay with ground fault protection

Electric Power Systems Research, 1996
Abstract This paper presents the design and construction of overcurrent and directional overcurrent relays with ground fault protection for the protection of three-phase subtransmission and distribution systems, using a 16-bit microprocessor, the Intel 8096BH. The relay obtains the system currents at the rate of 12 samples per cycle and estimates the
