SpletThe paper describes a series of tests carried out on 6.6 kV power-station induction motors to determine their fault-current contribution in the event of short circuits on the supply system. Results are given in the form of graphs showing the variation of peak and asymmetrical breakingcurrent contributions as a function of time after the fault. SpletThe total three-phase short circuit current at a faulted point includes both the currents from the power source (such as electric utility company or in-plant generators) and …
