The SIL-V is a voltage and frequency protection relay and represents the best and precise protection solutions 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 (Islanding) Protection.

It requires an auxiliary power supply of 24-230Vdc/ac and uses a circuit breaker as a cut-off element to protect a feeder. Notable for the 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 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.

    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.
    • States reading
    • Measurements reading
    • Reading and changing settings
    • Reading and changing configuration
    • Reading and deleting events

    • 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.
