1 SIL-G Feeder & Generator Protection Relay RC FLSH Main characteristics The SIL-G is a relay for primary distribution which can protect a feeder by means of current and voltage functions. It is also provided with the main functions to protect a generator protecting decoupling, load shedding and loss of main (islanding). It is normally used with a circuit breaker as cutting element. SIL-G can work with auxiliary power supply - Vdc/8-3 Vac, 8-3 Vdc/ac, -8 Vdc or in self-powered mode through the VTs (depending on model). Capability of measuring up to. 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 system. If this situation is not detected, then the generator could remain connected, causing a safety hazard within the network. utomatic 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. U lity network Interconnected P sys system Q sys rc Flash detection (FD) with FD inputs and high-speed outputs available depending on model. 79 protection function (Recloser) allows up to attempts of reclosing which can be programmed by the user. SIL-G has metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature. Direct signaling/control of the circuit breaker (5 function), of the recloser (79 function) and the communications local/remote control. P gen Q gen To allow the communication locally, relays have a front US 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 RS85: Modbus RTU, DNP3. Serial or IEC Ethernet rear port RJ5: Modbus TCP/IP, DNP3. TCP/IP or IEC 685 Fiber Optic: redundant communication (HSR IEC 685) larms panel is available. SIL-G 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 line voltage (optional for the model with NSI 5), positive sequence voltage and negative sequence voltage. Current angle for each phase and neutral (referred to V). Voltage angle per each phase and neutral (referred to V-). Phase Line voltage angle (optional for the model with NSI 5).

Up to oscillographic records and fault reports (5 cycles in total considering the number of cycles configurable to 5, 3 or 6 cycles), load data profiling with up to 6 records and 8 events can be recorded in non-volatile RM memory maintaining the date and time thanks to its internal RTC (Real Time Clock).
