A fault indicator for indicating the occurrence and relative direction of a fault current in a power transmission or distribution system includes a rotatably mounted indicator flag. The indicator flag is actuated 90° clockwise or counterclockwise from a central reset position to up-line indicating or down-line indicating trip positions by a compact magnetic pole piece assembly having three radially extending magnetic pole segments which interact with four magnetic poles on a magnetic armature rotatably coupled to the indicator flag. A pair of magnetic windings magnetize the pole segments upon the occurrence of a fault current to rotate the flag from the reset position. A second pole piece and winding directionally actuated in response to the direction of the fault current determines the direction of rotation of the indicator flag to indicate whether the fault is upline or downline relative to the indicator.
