Latest Patents
Feldman's latest patents include innovative methods for non-destructive status determination of electric power cables. One patent describes a method and apparatus for identifying and determining the energization status of a cable that features a conductive neutral member and an internal resistive screen layer. This invention utilizes radially movable probes to contact the neutral member and the internal resistive screen. The system employs narrow-band AC signals and resistance measurements for self-testing and cable testing, with a microprocessor controlling the probe-heating process. This allows the probes to advance through the plastic sheath to reach the neutral wire and resistive screen layer. The resistance measurements are monitored as the probes advance, while oscillators provide distinctive signals indicative of the cable's energization status.
Another patent focuses on cable status testing, which involves a method and system for determining the status of power distribution cables. This method includes the removal of a small plug from the sheath to expose an area of resistive material that can be probed to detect the presence or absence of a signal of predetermined frequency. The apparatus is equipped with self-testing circuits and circuits for determining resistance between the resistive layer and the sheath, ensuring positive identification of the cable being tested. The apparatus can be clamped directly to the cable and controlled from a remote location, enhancing operator safety.
