Abstract
A current sensing system includes a number of remote current sensors for measuring the magnetic field surrounding each conductor of an electrical transmission system to independently monitor the current flowing through the conductors. A generally U-shaped mounting fixture is provided for supporting the current sensors in a fixed, predetermined orientation relative to each of the conductors. An electronic compensation circuit is provided for conditioning the output of each the sensors with the output of the other of the sensors to isolate the influence of the magnetic field induced by the current flowing through only one of the conductors.
