The 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. | 04-07-2016 |

| 20090027062 | PARTIAL DISCHARGE DETECTION DEVICE - The present invention provides a high-performance partial discharge detection device which is user-friendly and compact and which allows detection of the electromagnetic waves caused by partial discharge, over a wide bandwidth with a simple constitution and a favorable S/N ratio. The waveguide antenna which receives electromagnetic waves that leak from the insulating spacer is attached to the outer circumferential face of the insulating spacer. The waveguide antenna is constituted by a waveguide portion and a coaxial cable connector which is installed on the waveguide portion. The waveguide portion has a metal short-circuit plate provided at one end thereof, and an opening formed at the other end thereof, which covers part of the outer circumferential face of the insulating spacer. | 01-29-2009 |
| 20090322345 | INSULATION COATED CONDUCTOR INSPECTION METHOD AND INSPECTION APPARATUS - In an insulation coated conductor inspection method for inspecting an electrical insulation characteristic of an insulation coated conductor in a coil formed by winding the insulation coated conductor, the coil is disposed in a test container, an internal pressure of the test container is reduced, an electrodes are provided so as to face the coil with a gap therebetween, an alternating-current voltage is applied between the electrodes and the coil, a generation frequency of a discharge that is generated between the coil and the electrodes upon application of the alternating-current voltage is measured, and the coil is determined to be a non-defective product having a superior electrical insulation property when the generation frequency of the discharge is higher than a reference generation frequency and determined to be a defective product having a defective electrical insulation property when the generation frequency of the discharge is lower than the reference generation frequency. A predetermined range is preferably set as a range in which a discharge charge amount is no greater than 100,000 (pc). | 12-31-2009 |
