Abstract: A tester applies a high-voltage test signal across the probes of a high-voltage measuring apparatus, wherein at least one of the probes is mounted at a probe end of an elongated insulated pole. The tester includes a battery-powered generator for generating the test signal which is applied across two contact terminals, respectively adapted for connection to the probes. One of the contact terminals is disposed at the bottom of an elongated tubular socket which receives the probe end of the pole, the contact terminal including two conductive members spring-biased apart until the pole is inserted in the socket. The generator is energized through a switch which may be mounted on the generator housing. In one embodiment the other contact terminal is an alligator clip and in a second embodiment the other contact terminal is disposed in a second socket.

Abstract: The ammeter includes a tubular housing with a hook-shaped sensor secured thereto at one end thereof and coupled to battery-powered digital ammeter circuitry disposed within the housing. The other end of the housing is open and receives telescopically therein a cylindrical cartridge which includes either a cradle or a recess supporting a replaceable battery and carrying connectors for connecting the battery to the ammeter circuitry. A universal spline coupler is telescopically received in a bore in the cartridge and projects from the tubular housing when the cartridge is disposed therein for coupling to associated equipment, such as a hot stick.

Abstract: A cable connector jacket formed of flexible, electrically insulating plastic is of unitary, one-piece construction, including two cavity-defining bodies hingedly interconnected in a clamshell-type configuration for movement between open and closed conditions. Each body has two pairs of channel-like tapered arms respectively extending in opposite directions therefrom generally parallel to the hinge line. When the bodies are in their closed conditions, the cavities define a chamber for accommodating the cable connector, and the arms of one body respectively mate with those of the other body to form four tapered tubes for respectively accommodating cable portions interconnected by the connector. A latch on the body holds the jacket closed.
