Abstract: In this study is presented a new algorithm based on logical functions to detect open phase fault in its two cases (open phase fault point before and after voltage sensor) in AC currents electrical power networks. This algorithm is based on RMS and phase angles values of three phases voltages and currents as input values of detection system that is basically based on logical functions. This system is applied on three phase electrical power network of sinusoidal voltage. It can also be applied on PWM voltage that must be filtered to get its fundamental RMS value. Simulation program was developed in Matlab/Simulink/PLECS software. Simulation results are presented.
