CA 2696216

Systems and methods are shown for detecting a blown fuse in a three-phase line by comparing neutral points in the line before and after the fuses. Diode rectifier circuits may be used to compare the neutral points and generate a DC output voltage when neutral points are off from one another, and photocoupler circuits may provide electrical isolation when signaling a neutral point shift. The neutral points compared need not be on immediate sides of the fuses, so intermediate components may exist, and in some embodiments one of the compared points may be within a load connected to the three-phase line.
