Advanced Distribution Keeps Korea Plugged In | TD World

Network Performance During The RainfallDistribution Automation System BackgroundConfigurationState of ImplementationThe BenefitsCompanies mentionedEarly in the morning on July 27, three fault-alarming indicators appeared simultaneously on the monitoring screen in the Gangnam DCC in Seoul. Triggered by faults, the current transformers installed in the switchgear on the source side of the fault position detected the fault currents, and the remote terminal units (RTUs) in the switchgear instantly sent messages to the DCC. Also included in the information from the fault-alarming indicators was the real-time load current on those feeders. Once the operators in the DCC confirmed the faulty sections of the network, the remote-control function started to open the adjacent switchgear to isolate the faulty sections and close the normally open switchgear to restore power to the healthy sections of each feeder. This entire process was completed within 3 minutes on average, and KEPCO repeated this process for the rest of the faults throughout the day, thereby minimizing the number of customers experiencing supply interruptions.

Artillery - Wikipedia

Artillery PieceCrewEtymologyHistoryAmmunitionField Artillery SystemClassification of ArtilleryModern OperationsUse in MonumentsReferencesAlthough not called as such, siege engines performing the role recognizable as artillery have been employed in warfare since antiquity. The first known catapult was developed in Syracuse in 399 BC. Until the introduction of gunpowder into western warfare, artillery was dependent upon mechanical energy which not only severely limited the kinetic energy of the projectiles, it also required the construction of very large engines to store sufficient energy. A 1st-century BC Roman catapult launching 6.55 kg (14.4 lb) stones achieved a kinetic energy of 16,000 joules, compared to a mid-19th-century 12-pounder gun, which fired a 4.1 kg (9.0 lb) round, with a kinetic energy of 240,000 joules, or a 20th-century US battleship that fired a 1,225 kg (2,701 lb) projectile from its main battery with an energy level surpassing 350,000,000 joules. From the Middle Ages through most of the modern era, artillery pieces on land were moved by horse-drawn gun carriages. In the contemporary era, artillery...Get price
