  • Patent number: 8866487
    Abstract: A directional fault sectionalizing system that utilizes one phase voltage measurement and three phase current measurements to determine the directionality of high impedance faults on a three phase electric power circuit. This eliminates the need for two of the three voltage measuring devices at each monitoring station conventionally required to determine fault directionality, which makes it economical to install at a greater number of distribution tap points. The system is particularly useful for commonly used three-way tap points along distribution lines where three phase voltage measurement is not readily available. The system is capable of identifying faults under challenging circumstances, such faults occurring on unbalanced three phase power lines and faults occurring on tapped line segments where the currents are relatively small compared to the currents flowing in the main line segments.

  • Publication number: 20060165855
    Abstract: A method and system for altering the interaction of wine ingredients to obtain changes in wine resembling many years of natural aging, a more complete homogenous solution, and an extended shelf life. The method includes application of ultrasonic radiation to a solution containing wine ingredients at a frequency causing cavitation, optimizing the application of ultrasonic radiation to cause cavitation throughout the solution, and continuing the application of the ultrasonic radiation for a duration sufficient for the cavitation to produce a consumable wine product. The system provided implements the described method.
