Detail SIL-A OC&EF Line Protection Relay

Overcurrent and Earth Fault Protection Relay for Primary and Secondary Distribution

The current measurement is obtained either by standard current transformers /1 or /5, or by special Low Power Current Transformers (LPCT).

Main characteristics:

  • Many Protection functions by default: 50P(2), 50N/G(2)(*), 50/51P, 50/51 N/G(*), 50BF, 46, 52, 79, 74TCS, COLD LOAD PICK-UP, 86, 49T . Optionally 49, 74CT, 37, 46BC, Trip Block for switch disconnector.
  • SIL-A adaptation B with Trip Bus protection function available through configurables inputs and outputs.
  • Auxiliary power supply (110-230 Vac/90-300 Vdc, 24-48 Vdc or 24-110 Vdc/48-230 Vac).
  • Metallic Box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.
  • Reduced size and light weight, easy to install and saves costs.
  • Direct signalling/control of circuit breaker (52 function) and recloser (79 function).
  • To allow communication, relays have a communication port on the front of the equipment and remote communication with different options:
    • One rear port on the back with the following options respect to protocols:
      • IEC60870-103 or Modbus RTU selectable by settings
      • IEC 61850, DNP3.0 or IEC 60870-5-104 (depending on the model)
    • Two rear ports on can be used simultaneously:
      • ModBus RTU and IEC60870-5-103, IEC 61850, DNP 3.0 or IEC 60870-5-104.
  • Inputs and outputs configurable, trip circuit supervision (74TCS function).
  • Oscillographic records, fault reports and non-volatile RAM memory: stores multiple events with date/time even without power supply thanks to its internal RTC.
  • Adaptation B is fitte with the demand of current with; 168 records, circular mode of recording and sampling rate (configurable through communications from 1 to 60 minutes)

(*) LPCT model: neutral current is calculated so overcurrent protection functions are 50N(2) and 50/51N.

(*) Compact model: neutral current is measured so overcurrent protection functions are 50N/G(2), 50/51 N/G
