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.
