nondir Trip at
V=0 Only relevant for current protection
modules/stages with directional feature! The
device will trip non directional if this
parameter is set to active and no direction
could be determined because no reference
voltage (V=0) could be measured any more
(e.g. if there is a three-phase short circuit
close to the device). If this parameter is set
to inactive, the protection stage will be
blocked in case of V=0.

of Vn: Vn is dependent on the System
Parameter setting of "VT con". When the
System Parameters "VT con" is set to
"phase-to-phase" , "Vn = VT sec ". When the
System Parameters "VT con" is set to

Meas Circuit
Superv
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).
