Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price

High-voltage direct current - Wikipedia

High Voltage TransmissionHistoryComparison with ACCostsConversion ProcessConfigurationsCorona DischargeApplicationsAdvancements in UHVDCFurther ReadingHigh voltage is used for electric power transmission to reduce the energy lost in the resistanceof the wires. For a given quantity of power transmitted, doubling the voltage will deliver the same power at only half the current. Since the power lost as heat in the wires is directly proportional to the square of the current, doubling the voltage reduces the line losses by a factor of 4. While power lost in transmission can also be reduced by increasing the conductor size, larger conductors are heavier and more expensive. High voltage cannot readily be used for lighting or motors, so transmission-level voltages must be reduced for end-use equipment. Transformers are used to change the voltage levels in alternating current(AC) transmission circuits. Transformers made voltage changes practical, and AC generators were more efficient than those using DC. These advantages led to early low voltage DC transmission systems being supplanted by AC systems around the turn of the 20th century. Pra...Get price

Infrared Inspection of Electric Utility Equipment

AbstractIntroductionPower GenerationSubstationsTransmission and DistributionConclusionsUnexpected failures in a utility provider’s electrical equipment can result in lost customer minutes and damage to valuable equipment. They can also undermine consumer confidence in their power provider. Routine infrared inspections coupled with effective repairs can pay huge dividends for electrical utilities by helping to reduce unscheduled downtime. Drawing upon a database compiled from over seven years of infrared inspections of electric utility equipment, this paper will discuss common problems such as connections and lightning arrestors as well as some not so common problems associated with oil filled equipment and insulators.Get price
