High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Direct current — (red curve). The horizontal axis measures time; the vertical, current or voltage. Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and… … Wikipedia
High voltage switchgear — is any switchgear used to connect or disconnect a part of a high voltage power system. These switchgear are essential elements for the protection and safe operation, without interruption, of a high voltage power system. This type of equipment is… … Wikipedia
High voltage — The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X… … Wikipedia
Direct on line starter — A direct on line starter, often abbreviated DOL starter, is a widely used starting method of electric motors. The term is used in electrical engineering and associated with electric motors. There are many types of motor starters, the simplest of… … Wikipedia
Traction current line — A traction current line is a high voltage transmission line for the supply of railways with traction current for powering locomotives. A network of traction current lines is needed in countries where trains use single phase alternating current of … Wikipedia
Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia
Direct torque control — (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors. This involves calculating an estimate of the motor s magnetic flux and torque based on the measured… … Wikipedia
Voltage drop — is the reduction in voltage in an electrical circuit between the source and load. In electrical wiring national and local electrical codes may set guidelines for maximum voltage drop allowed in a circuit, to ensure reasonable efficiency of… … Wikipedia
Electrode line — Under an electrode line one understands the line connection from the static inverter plant of a high voltage direct current transmission from to the grounding electrode (cathode or anode). The grounding electrode is for the prevention of electro… … Wikipedia
Rome-Fiuggi railway line — The Rome Fiuggi railway line is a former railway built on the east part of Rome, Italy. It consisted of km to mi|78.1 of rail from Rome to Fiuggi.HistoryOn March, 1907 the Superior Council of Public Works gave its fiat to build the line, which… … Wikipedia
