SIPROTEC 5

SIPROTEC 5

Siemens have released information on the new SIPROTEC 5 series of protection relays. There are outstanding advances in the features and capability offered by this new generation of technology. This range is focused on supporting the needs of advanced transmission applications, and answering the call for powerful security and flexible communications capabilities.

The release of SIPROTEC 5 does not affect SIPROTEC 4, which continues to be fully supported with ongoing development. SIPROTEC 4 is still the product for most of our customers standard applications, as the focus of SIPROTEC 5 is for advanced (Transmission) applications needing specific new capability.

SIPROTEC 5 has been initially released to address the needs of customers with breaker and a half applications. We expect the next major release will be to address Transformer Protection applications. The HV Power team will keep you up-to-date as products are released.

With this new hardware range, you will encounter DIGSI 5, a very powerful piece of software that supports the features of SIPROTEC 5. DIGSI 5 currently only supports SIPROTEC 5. DIGSI 4 continues to be developed and supported for SIPROTEC 4 applications. Note however, that the product roadmap for DIGSI 5 does include its eventual backward compatibility to also support SIPROTEC 4 (and earlier products). We will keep you posted!

Line Differential Protection


Solkor R/Rf (7PG21)

REYROLLE Solkor-N

Solkor R/Rf Electromechanical pilot wire relay for copper pilot wires. Solkor R/Rf relays are well known and proven for their simple, traditional and reliable approach to differential line protection operating over copper pilot wires. Installation is simplified with no need for auxiliary supply circuits. Intertripping and pilot wire supervision products also available, however for these more complex protection requirements, we recommend the Siemens SIPROTEC 7SD80.

  • Simple, reliable, no auxiliary DC required
  • mA loop current used over single pilot pair, so relatively immune to interference and condition of pilot
  • One plug setting
  • No SCADA interface

Arc Fault Monitoring

Arc fault monitoring offers a method of very rapid clearance of faults within metal clad switchgear and associated cable boxes. Sensors detect the optical signature of the onset of an arc fault and a trip signal can be achieved within 10 ms, considerably faster than traditional IDMT overcurrent relays – especially as the onset of an arc fault can occur at relatively low fault currents. Multiple sensors and zones can be configured to trip feeder, bus coupler or incoming breakers as required.

Also available are the Siemens 7PA30 Three phase and single phase trip circuit supervision relays. See the SIPROTEC 4 catalogue for further details.

 

Voltage Selection Relays

RMS 2P48

The 2P48 relay is a Voltage Selection Relay for the automatic changeover between two VT supplies. The relay is designed to automatically change over from the primary supply to the secondary supply if any phase of the primary supply has faulted. Each of the incoming phases for both primary and secondary supplies have LED indicators to indicate healthy supplies. The outgoing phases are also indicated. Monitoring for excessive negative sequence voltage resulting from phase failure, phase unbalance and reversed phase sequence is provided.

Note the 2P48 is designed for three phase supplies and requires a neutral connection. If this is not available then 2P49 version should be used.
