HVDC (High Voltage Direct Current) transmission system dates back to the 1930s when mercury arc rectifiers were invented. Since the 1960s‚ HVDC transmission system is now a mature technology and has played a vital part in both long distance transmission and in the interconnection of systems. Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. HVDC transmission systems‚ when installed‚ often

Mass media has also negatively impacted the foundation of religion because it has allowed for the loss of the core meaning of the religion’s belief infrastructure during transmission. Historically‚ this form of communication works against established religious values. The relationship between mass

Merchant power plants differ from traditional rate-based power plants as to: 1) how they are financed and 2) where they sell the electricity they generate. A merchant power plant is funded by investors and sells electricity in the competitive wholesale power market. Since a merchant plant is not required to serve any specific retail consumers‚ consumers are not obligated to pay for the construction‚ operations or maintenance of the plant. A traditional rate-based power plant‚ on the other hand

ABSTRACT: This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit‚ which is connected to the power line through the high voltage coupling capacitors of the CVT. Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record
