On April 16, 2013, an attack was carried out on Pacific Gas and Electric Company's Metcalf transmission substation in Coyote, California, near the border of San Jose.The attack, in which gunmen fired on 17 electrical transformers, resulted in more than $15 million worth of equipment damage, but it had little impact on the station's electrical power supply.
The Pacific Intertie consists of: [4] The Celilo Converter Station which converts three phase 60 Hz AC at 230 to 500 kV to ±500 kV DC (1000 kV pole-to-pole) at . The grounding system at Celilo consists of 1,067 cast iron anodes buried in a two-foot (60 cm) trench of petroleum coke, which behaves as an electrode, arranged in a ring of 2.0 miles (3,255 m) circumference at Rice Flats (near Rice ...
The Los Angeles Downtown Industrial District (LADID) is manufacturing and wholesale district of downtown Los Angeles, California, that was established as a property-based business improvement district (BID) in 1998 by the Central City East Association (CCEA). The district spans 46 blocks, covers 600 properties, and is the historic home of ...
The Sylmar Converter Station is the southern converter station of the Pacific DC Intertie, an electric power transmission line which transmits electricity from the Celilo Converter Station outside The Dalles, Oregon to Sylmar, a neighborhood in the northeastern San Fernando Valley region of Los Angeles, California.
Wild windings are mostly applied in contactor- and relay coils, small transformers, Ignition coils, small electrical motors, and generally devices with relatively small wire gauges up to 0.05 mm. Achieved fill factors with the use of round wires are about 73% to 80% and are lower compared to orthocyclic windings with 90%.
A conventional six-winding, grounding transformer or zigzag bank, [1] with the same winding and core quantity as a conventional three-phase transformer, can also be used in zigzag winding connection. In all cases the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core.
In electrical engineering, an autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting alone. In an autotransformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer. In contrast, an ordinary transformer ...
States with areas largely affected by the Southwest Blackout of 2011. The 2011 Southwest blackout, also known as the Great Blackout of 2011, [1] [2] was a widespread power outage that affected the San Diego–Tijuana area, southern Orange County, Imperial Valley, Mexicali Valley, Coachella Valley, and parts of Arizona.
