Level detector
The measured phase currents are compared phasewise to the set Start value. If the
measured value exceeds the set Start value, the level detector reports the exceeding
of the value to the phase selection logic. If the ENA_MULT input is active, the Start
value setting is multiplied by the Start value Mult setting.
The IED does not accept the Start value or Start value Mult setting
if the product of these settings exceeds the Start value setting range.
The start value multiplication is normally done when the inrush detection function
(INRPHAR) is connected to the ENA_MULT input.
