The fault-related current, voltage, frequency, angle values, shot pointer and the active
setting group number are taken from the moment of the operate event, or from the
beginning of the fault if only a start event occurs during the fault. The maximum
current value collects the maximum fault currents during the fault. In case frequency
cannot be measured, nominal frequency is used for frequency and zero for Frequency
gradient and validity is set accordingly.
Measuring mode for phase current and residual current values can be selected with the
Measurement mode setting parameter.
