Record Size Electrical Equipment for Los Angeles. — Two of the world´s largest hydrogen-cooled synchronous condensers will be built by the General Electric Co. for the bureau of power and light, City of Los Angeles, to be installed on the receiving end of the 270-mile transmission line from Boulder Dam. These machines will be rated at 60,000 kva, 13,800 volts, 60 cycles. The installation will be an example of one of the standard applications for synchronous condensers where they perform the function of controlling the power factor of the load so that regulation and losses of the line can be held within reasonable values, thereby controlling within limits the voltage of the receiving bus. Hydrogen cooling results in materially reducing windage losses with a corresponding saving in operating expense. The machines will be installed outdoors.
