LOP Blo Activates the use of the measuring circuit supervision. In
this case the module will be blocked if a measuring circuit
supervision module (e.g. LOP, VTS) signals a disturbed
measuring circuit (e.g. caused by a fuse failure). Inactive,

t-LVRT This timer defines the supervision interval
(window/period) for counting the number of voltage dips
to trip (“No of V dips to trip”). The first voltage ip will start
the timer. The counted number of voltage dips will be
reset if the timer is expired. The timer will also be reset if
the maximum “No of V dips to trip” is reached.
Only available if:AR controlled LVRT = Active
