A self powered parallel bar current sensor for generating a signal which accurately represents current in a power line includes a power coil core having an opening extending therethrough, and a current sensing element including two substantially parallel sensing bars and a sensing coil. The sensing coil is disposed between the sensing bars, and the sensing bars and sensing coil extend through the power coil core opening. A reference coil may also be situated between the sensing bars. The current sensor is connected in series in the power line.
