Prospective Short Circuit Current

Prospective Short Circuit Current

The prospective short circuit current (PSCC) is the highest electric current which can exist in a particular electrical system under short-circuit conditions. It is determined by the voltage and impedance of the supply system. It is of the order of a few thousand amperes for a standard domestic mains electrical installation, but may be as low as a few milliamperes in a SELV (Safety Extra Low Voltage or, occasionally, Separated Extra Low Voltage) system or as high as hundreds of thousands of amps in large industrial power systems.

Famous quotes containing the words current, circuit and/or short:

    We hear the haunting presentiment of a dutiful middle age in the current reluctance of young people to select any option except the one they feel will impinge upon them the least.
    Gail Sheehy (b. 1937)

    We are all hostages, and we are all terrorists. This circuit has replaced that other one of masters and slaves, the dominating and the dominated, the exploiters and the exploited.... It is worse than the one it replaces, but at least it liberates us from liberal nostalgia and the ruses of history.
    Jean Baudrillard (b. 1929)

    The believing mind reaches its perihelion in the so-called Liberals. They believe in each and every quack who sets up his booth in the fairgrounds, including the Communists. The Communists have some talents too, but they always fall short of believing in the Liberals.
    —H.L. (Henry Lewis)
