beginning of the fault if only a pickup 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.
