SIL-B – Feeder Protection Relays

SIL-B Relays are for primary distribution which is ideal to protect a feeder by means of current and voltage functions and it is normally used with a circuit breaker as cutting element.

Aasy mounting, and fast settings make the SIL-B series the right solution for industrial and utility feeder protection. SIL-B provides complete feeder protection, with overcurrent, overvoltage, undervoltage, directional

Uses auxiliary power supply 110-230 Vac/90-300 Vdc or 24-48 Vdc.

Its reduced size makes the SIL-B series relays iasy to install and its light weight helps the customer to save costs in transport.

Features

The SIL-B is a relay for primary distribution which is able to protect a feeder by means of current and voltage functions. It is normally used with a circuit breaker as cutting element.

SIL-B is used with auxiliary power supply 110-230 Vac/90-300 Vdc or 24-48 Vdc.
Protection functions available in SIL-B are the following:
- 50 (2), 50N/G (2), 67 (2), 67N (2), 46, 59 (2), 59N (2), 27 (2), 32/40 (4), 79, 50BF, 52, 49, 86 Cold Load Pick-up, 49T, 74TCS.
- Optionally: 81 U/O, 25, 37 and IRIG-B.
79 protection function (Recloser) allows up to 5 attempts of reclosing which can be programmed by the user.
SIL-B has metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.
Its reduced size makes the SIL-B relay easy to install and its light weight helps the customer to save costs in transport.
Direct signalling/control both of the circuit breaker (52 function), both of the recloser (79 function).
To allow the communication relays have a communication port on the front of the equipment.
Two rear ports on the back for remote communication. Two communication protocols can be used simultaneously:
- MODBUS RTU
- IEC 60870-5-103, IEC 61850, DNP 3.0 or IEC 60870-5-104.
SIL-B can show different measurements like:
- Phase r.m.s. currents, neutral r.m.s. current, positive / negative sequence currents.
- Phase r.m.s. voltages, residual neutral voltage r.m.s, voltage between phases and Busbar phase voltage.
- Angle current of each phase respect to phase A voltage.
- Cos Phi (power factor and each phase power factor).
- Active power, reactive and apparent power (Total power and each phase power).
- Line frequency and Busbar frequency.
- Phase difference between phase B line voltage and busbar voltage.
The SIL-B has 8 configurable inputs and 7 configurable outputs.
2 Oscillographic records, non-volatile RAM memory in order to store up to 1.000 events and 20 fault reports, without power supply thanks to its internal RTC (Real Time Clock).

Software

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.

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.
