... The effect of utility impedance on the operation of a drive is a function of how stiff or soft the line is. Nominally (i.e. %Z = 1%), the drive short circuit current is set at 100 times the drive rating. On a soft line (i.e. %Z > 10%), the short circuit rating is 10 times the drive’s rating; and on ...

Voltage regulator
A voltage regulator is designed to automatically maintain a constant voltage level. A voltage regulator may be a simple ""feed-forward"" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line.
