Patent number: 10290416Abstract: Exemplary embodiments of the present disclosure are directed to resonant transformers (or reactors) and coil arrangements associated with resonant transformers. The coil arrangements can include a grounding coil configured to generate a net-zero induced voltage between a first end of the grounding coil and a second end of the grounding coil layer, and one or more step-up coil layers formed by one or more layers of pressure tape, insulating materials, and wire wrapped to form coils about a portions of a split magnetic core. The split magnetic core can include a first core segment and a second core segment, where one of the core segments is disposed within a main housing and one of the core segments is disposed external to the main housing. A gap between the first and second core segments can be manipulated to control an inductance of the resonant transformer.Type: GrantFiled: June 12, 2017Date of Patent: May 14, 2019Assignee: Instrument Manufacturing CompanyInventors: Matthew S. Mashikian, Andrzej Pawel Szatkowski

Patent number: 9964581Abstract: A resonant test system can be configured to adjust an inductance to set the inductance of the resonant test system to a test inductance value and to adjust an output frequency of the resonant test system to set the output frequency to a test output frequency. The inductance of the resonant test system can be adjusted by controlling a reactor of the resonant test system and the output frequency of the resonant test system can be controlled by an inverter of the resonant test system. The test inductance value and the test output frequency the test inductance value and the test output frequency can be automatically and dynamically set by a controller of the resonant test system to achieve resonance in series with an electrical power cable under test. One or more diagnostic tests can be performed on the electrical power cable.Type: GrantFiled: October 3, 2014Date of Patent: May 8, 2018Assignee: Instrument Manufacturing CompanyInventors: Andrzej Pawel Szatkowski, Matthew S.

Patent number: 7705607Abstract: The present disclosure is directed to cable diagnostic test methods, systems and apparatus that advantageously utilize “standing wave”principles to facilitate the identification and location of defect(s) along a power cable. The disclosed methods/systems are effective in measuring dissipation factors and dielectric constants associated with shielded power cable insulation at any number of points or sections along the axial length of the cable. In essence, the disclosed methods/systems perform what may be termed axial tomography, allowing the dielectric loss or dissipation factor and the dielectric constant of the insulation as well as the resistance and inductance of the cable conductor system to be determined at one or more pre-determined points/sections of the cable along its axis.Type: GrantFiled: August 24, 2007Date of Patent: April 27, 2010Assignee: Instrument Manufacturing CompanyInventor: Matthew S.
