Abstract
A device for testing a conductor for the presence of high AC voltage includes a voltage detection circuit connected to a probe assembly, preferably designed for insertion in the access bushing of an underground electrical transmission or distribution equipment. The probe assembly includes an elongated tubular insulating housing with a conductive probe at one end and a threaded connector at the other end for connection to the detection circuit. A high resistance, preferably several megohms, is connected in series between the tip and the connector and is preferably comprised of a plurality of series-connected resistors encased in a heat shrink tubing.
