Details:
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).
