Figure 122: Operating zones at minimum magnitude levels
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 protection relay 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.
