Abstract
Methods and apparatus are described to quickly and easily identify live URD elbow connectivity between junction cabinets in underground electric utility power distribution circuits so URD connected elbows can be correctly tagged. A first method segregates elbows in a cabinet into input elbows from an upstream cabinet, output elbows to a downstream cabinet, and by phase attribute. A second method injects a tracer signal into the elbow capacitive test point of an upstream output elbow and detects the tracer signal at the elbow capacitive test point of a downstream elbow capacitive test point to identify connectivity. A third method compares the output current of an upstream output elbow to that of the input current of a downstream input elbow to identify connectivity.
