Superconducting Power Transmission by Low Voltage Cable

Power Cable Protection in Transmission System

Power cable is widely used in Extra High Voltage (EHV), High Voltage (HV) transmission, Medium Voltage (MV) sub-transmission, and MV / Low Voltage (LV) distribution applications. Basically, the protection principles used for cable are similar with the ones for overhead transmission line. However, the inherent characteristics of cables make its fault behavior more complicate than that of transmi...

Low Power Nonvola Voltage

This paper presents a new nonv design that incorporates low-voltag PMOS Flash transistors. The de global store, restore and erase o negligible penalty on regular SRA Store/erase operations also do not c power even considering charge Circuit simulations based on exp characteristics demonstrate that 10 operation at ± 6 V is sufficien restoration of the stored bit even und process variation.

Return to Session DEVELOPMENT AND DEMONSTRATION OF A LONG LENGTH TRANSMISSION VOLTAGE COLD DIELECTRIC SUPERCONDUCTING CABLE TO OPERATE IN THE LONG ISLAND POWER AUTHORITY GRID

The US Department of Energy is funding the world’s first cold dielectric superconducting power cable demonstration project at transmission level voltage, to be installed at the Long Island Power Authority (LIPA) grid in 2007. The cable is designed to carry 574 MVA at a voltage of 138 kV. It will remain installed as a permanent part of the LIPA grid. The project team is comprised of American Sup...

A Class E Power Amplifier with Low Voltage Stress

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
