SIL-V – Voltage & Frequency Protection Relays

The SIL-V is a voltage and frequency protection relay and represents the best and precise protection soluctions for transformers and electrical machines, in high, medium and low voltage distribution systems. Also protects decoupling, load shedding and loss of main (islanding).

Hi-tech design that offers the greatest security and protection for Transformers or Electrical machines. For HV, MV and LV Distribution Systems and for Decoupling, Load shedding and Loss of main (Islading) Protection.

It requires auxiliary power supply of 24-220 Vdc/48-230Vac. and It uses a circuit breaker as a cut-off element to protect a feeder. Notable for capability of measuring up to 1.000 volts when it is connected directly to the low voltage line.

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 systems. If this situation is not detected, then the generator could remain connected, causing a safety hazard within network.

Automatic reconnection of the generator to the network may occur causing damage to the generator and the network.

SIL V protection relay detects this situation thanks to its voltage and frecuency functions focused on the Rate of change of frequency (ROCOF) method.

It uses a circuit breaker as a cut-off element to protect a feeder.
Capability of measuring up to 1.000 volts when it is connected directly to the low voltage line.
Protects decoupling, load shedding and loss of main (islanding).

Loss of Mains (islanding) occurs when part of the 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-V protection relay detects this situation thanks to its voltage and frequency functions focused on the Rate of change of frequency (ROCOF) method.

Metallic box with high electromagnetic compatibilitu level (EMC) and wide range of operating temperature.
To allow the communication it has a local ModBus RTU port on the front.
Depending on the model there are different options for communicartion rear ports:
- RS485 rear port with IEC60870-103 or Modbus RTU protocol selectable by settings.
- RJ45 rear port with IEC61850, DNP3.0, Modbus TCP/IP or IEC60870-104, depending on the model.
  The SIL-V has 6 inputs and 4 outputs salidas configurables by the user.
5 Oscillographic records, non-volatile RAM memory in order to store up to 200 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®7, Windows®8, Windows®8.1 y Windows®10 operating system.

General data reading: Complete model, Version, Serial number, etc.

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.
