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 short, circuit and/or current:

    In short I must confide in you to take such care of the men under you as an economical householder would of his own family, doing every thing within himself as far as he can, and calling for as few supplies as possible. The less you depend for supplies from this quarter, the less you will be disappointed.
    Thomas Jefferson (1743–1826)

    each new victim treads unfalteringly
    The never altered circuit of his fate,
    Bringing twelve peers as witness
    Both to his starry rise and starry fall.
    Robert Graves (1895–1985)

    Natural Man, in our current version, is a disgruntled adolescent.
    Mason Cooley (b. 1927)
