Recloser Control SIR-B

The innovative Fanox SIR-B Recloser Control is designed to provide optimum protective coordination and the most effective fault clearance of distribution systems.

ALL IN ONE

SIR-B includes the driving electronic and the trip capacitor and it can work with external battery or with super capacitors which allow the user to minimize the maintenance tasks internal.

It is designed to work with 3-phase reclosers, but it can provide single phase trips and reclose cycles, this is, it is provided with a monopolar circuit breaker control.

Furthermore, protects decoupling, load shedding and loss of main (islanding), and 79 protection function (Recloser) allows up to 4 attempts of reclosing which can be programmed by the user.

SIR-B includes the driving electronic and the trip capacitor and it can work withexternal battery or with super capacitors which allow the user to minimize the maintenance tasks.

The SIR-B is designed to work with 3-phase reclosers, but it can provide single phase trips and reclose cycles, this is, it is provided with a monopolar circuit breaker control

4 current inputs and 6 voltage inputs are included. The voltage inputs will depend on the selected model (standard voltage through VTs or LEA inputs)

The SIR-B offers a module to manage the energy:

  • Battery (12 Vdc) or Super capacitors (16 Vdc)
  • 3 Analog open/close outputs (trip capacitors options: 24 Vdc, 48 Vdc, 155 Vdc or 220 Vdc)
  • 12 Vdc output for 3G modem
  • 8 Digital inputs
  • 4 digital outputs

SIR-B works with auxiliary power supply 90-300 Vdc/110-230 Vac.

Protects decoupling, load shedding and loss of main (islanding). Loss of Mains (islanding) occurs when part of the public utility network loses connection with the rest of the system. If this situation is not detected, then the generator could remain connected, causing a safety hazard within the network. Automatic reconnection of the generator to the network may occur causing damage to the generator and the network. SIL-G protection relay detects this situation thanks to its voltage and frequency functions focused on the Rate of change of frequency (ROCOF) method.

Last gasp trip is included thanks to the Energy management Monitoring (EMM).

79 protection function (Recloser) allows up to 4 attempts of reclosing which can be programmed by the user.

SIR-B has metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.

Direct signaling/control of the circuit breaker (52 function), of the recloser (79 function) and the communications local/remote control.

To allow the communication locally, relays have a front USB port. Depending on model, WiFi local communication is available.

For remote communications several rear ports are available with the following protocols (depending on model)

  • Serial rear port RS485: Modbus RTU, DNP3.0 Serial or IEC 60870-5-103
  • Ethernet rear port RJ45: Modbus TCP/IP, DNP3.0 TCP/IP or IEC 61850
  • Fiber Optic: redundant communication (HSR – IEC 61850)

Alarms panel is available.

SIR-B can show different measurements like:

Phase currents, neutral (measured and calculated), maximum current, positive sequence current and negative sequence current.

Second harmonic current per phase.

Phase to neutral, phase to phase voltages, neutral voltage (calculated and measured), maximum voltage, phase B line voltage (optional for the model with ANSI 25), positive sequence voltage and negative sequence voltage.

Current angle for each phase and neutral (referred to VA). Voltage angle per each phase and neutral (referred to V-A). Phase B Line voltage angle (optional for the model with ANSI 25).

Active, reactive and apparent powers (3- phase and per phase).

Thermal image.

Line frequency and busbar frequency.

Rate of change of frequency.

Up to 100 oscillographic records and fault reports (1500 cycles in total considering the number of cycles configurable to 15, 30 or 60 cycles), load data profiling with up to 2160 records and 2048 events can be recorded in non-volatile RAM memory maintaining the date and time thanks to its internal RTC (Real Time Clock).

Communication Software for SIA & SIL Protection Relays

The SICom PC software has been designed and programmed to gain access to all of Fanox relays information, to modify the settings and configuration, check states and measurements and to analyse and save events and fault reports using a graphic-friendly user interface.

SICom software works with the Windows® Windows 7, Windows 8, Windows 8.1 and Windows 10 operating system.

  • General data reading: Complete model, Version, Serial number, etc.
  • States reading
  • Measurements reading
  • Reading and changing settings
  • Reading and changing configuration
  • Reading and deleting events
  • Reading and deleting fault reports
  • Reading and deleting demand current (load data profiling)
  • Reading and saving oscillographic records in Comtrade format
  • Changing the user passwords
  • Saving and Loading settings files
  • Saving and Loading configuration files
  • Saving events and fault reports
  • Saving demand current (load data profiling)
  • Date-time synchronization
  • Configuring the communication parameters
  • Reading and changing counters
  • Commands for opening and closing the circuit breaker and block/unblock the recloser
  • Configuration of the inputs
  • Configuration of the outputs
  • Configuration of the causes that start a Fault Report

The update of the software does not require any user´s action, this is, if the computer is connected to Internet, SICom updates itself when it is started.
It will allow you to prepare all the settings and relay configurations without having the relay connected to the PC (offline mode), reducing engineering and commissioning time.
SICom program uses Modbus protocol, so only the ports with this protocol can be used to establish the communication.
