Latest Patents
Dery's latest patents include an "Apparatus for sensing and measuring a current on power transmission line" and an "Energy extraction system from a capacitive source with shunt switching." The first patent describes an apparatus designed to sense and measure both DC and AC currents on low voltage (LV) and high voltage (HV) power circuits. This apparatus features a shunt element connected to the transmission line, with an electronic circuit housed in a conductive enclosure that shields it from thermal effects, magnetic fields, and electrostatic interference.
The second patent outlines a system for extracting energy from a capacitive source, such as the energy induced in an insulated section of an overhead wire on an AC transmission line. This system utilizes a voltage step-down transformer to tap into the overhead wire, regulating the AC voltage through shunt switching controlled by power thyristors. This innovative regulation method maximizes power extraction per kilometer of insulated wire and ensures stable output voltage, even with varying loads.
