LINE DIFFERENTIAL PROTECTION WITH DISTANCE BACKUP

DISTANCE PROTECTION

DISTRIBUTED BUSBAR PROTECTION

AUTOMATIC VOLTAGE REGULATOR

New brochure: HFLEX2410Iv00

For two to four winding transformers or autotransformers, of any voltage level, with single or double circuit breaker.


  • IDF-A: for two windings Transformers
  • IDF-B: for up to three windings transformers
  • IDF-E: for up to four windings transformers, or three windings' transformers with one winding on breaker-and-a-half

IDF: TRANSFORMER PROTECTION

For distribution feeders, transformers and
generators, transmission line backup, and
BCU (Bay Control Unit for single or double
circuit breaker).


  • IRF-A: MV Feeder Protection & Control
      • IRF-B: double breaker or breaker-and-
        a-half BCU
      • IRF-C: general alarms BCU / I/O Box.
      • IRF-D: single breaker BCU




IRF: MODULAR FEEDER PROTECTION

Both units are suitable for lines of any voltage level,
overhead or under ground, multiterminal, and single or
parallel circuits.


  • DLF-A: for single breaker
  • DLF-B: for double breaker or breaker-and-a-half, when
    CTs are at the line side (1 single set of 3 CTs)

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
