Abstract
Provided are a method and apparatus for monitoring a current of the ground wire of an armouring shielding cable in a strong electromagnetic environment. In the method, a summation of currents of the ground wires in the armouring layer and a summation of currents of the ground wires in the shielding layer of M cables in a terminal box are collected, and a primary ground copper busbar potential and a secondary ground copper busbar potential of the terminal box and a ground current of an adjacent terminal box are collected; a potential difference alarm can be achieved; and according to whether a potential difference is alarmed, terminal box cable loop loop-current alarms are performed respectively using different criteria.
