In developing countries, a pressure associated with economical and environmental constraints has forced the power utilities to meet the future demand by fully utilizing the existing resource of transmission facilities without building new lines. Flexible alternating current transmission systems (FACTS) devices are used to control the phase angle, voltage and impedance of high voltage AC lines. ...

Performance of sense amplifier has considerable impact on the speed of caches used in microprocessors. The small difference in voltage level of bit lines of memory cell is amplified by sense amplifier. voltage mode sense amplifier reduces the power dissipation during read and increases the speed also. This paper describes voltage mode sense amplifier and current mode sense amplifier and compare...

OBJECTIVE To determine whether there is an association between distance of home address at birth from high voltage power lines and the incidence of leukaemia and other cancers in children in England and Wales. DESIGN Case-control study. SETTING Cancer registry and National Grid records. SUBJECTS Records of 29 081 children with cancer, including 9700 with leukaemia. Children were aged 0-14...

In this paper, the effectiveness of lightning overvoltage protection cables in high voltage overhead cable lines has been analyzed. Because level, are protected by surge arresters and metallic sheath earthing. However, practice, quite a lot cases electricity-evoked damage to outer sheaths observed, proving that used is insufficient. As result, exposed environmental factors, especially moisture ...
