Setting Group Parameters of the 51R Ground Fault Protection
Parameter
Description
Function
Permanent activation or deactivation of module/element. Inactive,
ExBlo Fc
Activate (allow) or inactivate (disallow) blocking of the
module/element. This parameter is only effective if a
signal is assigned to the corresponding global protection
parameter. If the signal becomes true, those
modules/elements are blocked that are parameterized
"ExBlo Fc=active".
Rvs Blo Fc
Activate (allow) or inactivate (disallow) reverse blocking
of the module/element. This parameter is only effective if
a signal is assigned to the corresponding global
protection parameter. If the signal becomes true, those
modules/element are blocked that are parameterized
"Rvs Blo Fc = active".
Blo TripCmd
Permanent blocking of the Trip Command of the
module/element.
ExBlo TripCmd Fc
Activate (allow) or inactivate (disallow) blocking of the
module/element. This parameter is only effective if a
signal is assigned to the corresponding global protection
parameter. If the signal becomes true, those
modules/elements are blocked that are parameterized
"ExBlo TripCmd Fc=active".
Criterion
Measuring method: fundamental or rms or 3rd harmonic
(only generator protection relays)
Pickup
If the pickup value is exceeded, the module/element will
be started.
