DLF: LINE DIFFERENTIAL PROTECTION WITH DISTANCE BACKUP
Suitable for lines of any voltage level, single or double
circuit breaker with any configuration: overhead or
underground, single or parallel circuits.
- ZLF-B: for single breaker.
- ZLF-C: for double breaker or breaker-and-a-half.
ZLF: DISTANCE PROTECTION
Distributed busbar differential protection for up to 24
bays and 4 busbars, with Ethernet HSR or PRP
redundant communication between the central and
bay units, based on process bus IEC 61869-9 SV, IEC
61850-8-1 GOOSE and PTP IEC 61850-9-3.
Cost-Effective Solution
- The bay units, not only operate as SV publishers and
GOOSE publishers / subscribers but they can also be
used as Protection and Control IEDs, as they can run
the protection functions of a feeder relay. This makes
this solution very cost-effective for MV busbar
differential protection.
DBF: Distributed Busbar Protection
HSR redundancy between
central and bay units
PRP network between central
and bay units
