ABSTRACT:
A new type of immersible fault detector which includes a magnetic coupling link that can be coupled to a power line and a detector receives energy proportional to the load currents flowing in the power line and energizes a light source. A fiber-optics light waveguide or cable is connected to the detector so as to detect the light generated by the detector and has its opposite connected to an indicator which is remote from the detector and is electrically insulated therefrom so that the condition of the power line can be determined.
