Abstract
A faulted circuit indicator includes a variable load levelling circuit which can automatically adjust itself to a peak current in order to accommodate a relatively wide range of load currents. The variable load levelling circuit is operatively connected to a current sensing circuit and is responsive to a varying load current flowing through the cable for regulating a variable output voltage therefrom to be at a constant reference value. As a result, the need to store in inventory large quantities of fault indicators with different rated currents has been substantially reduced.
