Abstract
Synchronous measuring terminalssynchronously measure phasor quantity Dof a voltage/current at respective measurement points 1 and 2. A data-set creating blockof a short-circuit capacity monitoring devicecreates, for each measurement cycle Δt, a data set Dcontaining n pieces of data based on the phasor quantities Dof voltage and current. A phase correcting blockperforms a phase correction on the phasor quantity using the data set Dto create a data set D', and a backward impedance estimating blockestimates a backward impedance Dusing the data set D′.
