Instantaneous and blocking TRIP commands
The Z*G element is able to operate in an instantaneous mode by using the scheme switch
[Z1CNT_INSTOP]. Furthermore, the scheme switch [LEG_EN] can block this element. The
scheme switch [Z*G-PSBBLK] is selected for blocking the tripping when a power swing occurs
in the system. A residual overcurrent element (EFL) is provided as a common function. A value
can be set using the setting [EFL].
