500_kV_Switch1.jpg


This video clip was captured by the maintenance foreman at the 500 kV Eldorado Substation near Boulder City, Nevada. It shows a three-phase motorized air disconnect switcher attempting to open high voltage being supplied to a large three phase shunt line reactor.

The arc stretches upward, driven by rising hot gases and writhing from small air currents, until it easily exceeds 100 feet in length. Switching arcs usually terminate long before reaching this size since they normally flash over to an adjacent phase or to ground.

As impressive as this huge arc may be, the air break switch was really NOT disconnecting a real load. This arc was “only” carrying the relatively low (about 100 amps) magnetizing current associated with the line reactor. The 94 mile long transmission line associated with the above circuit normally carries over 1,000 megawatts (MW) of power between Boulder City, Nevada (from the generators at Hoover Dam) to the Lugo substation near Los Angeles, California. A break under load conditions (~2,000 amps) would have created a MUCH hotter and extremely destructive arc.

Back in the late 60's there was a proposal to build a barrage across the mouth of the Wash. This scheme involved a dam like structure with a road running the length of it and deep sea channels still leading to Kings Lynn and Boston harbours. Most of the Wash was to be drained, with further proposals for a race track around the Wash, Silverstone eat your heart out, more agricultural land and industrial areas. What remained of the Wash would have become fresh water. The circular object you describe is the remains of the Outer Bund, built I believe around 1972. There was originally an Inner Bund. These were trials to study the feasibility of building the barrage and the suitability and geology of the sea floor for such a project. As with many schemes of this nature it was eventually decided that the scheme would prove too expensive and it was abandoned.
