... Advances in Electrical and Computer Engineering Volume 11, Number 1, 2011 Measured quantities were line currents, neutral conductor current and grid voltages at the point of common coupling (PCC). The short-circuit current (ISC) at the PCC of the Computer centre was ISC=6kA. Measurement was conducted throughout 7 days, ...
