Argus-C

After extensive development, Reyrolle SPD have released a new overcurrent protection relay, perfect for NZ feeder protection applications. The ARGUS-C features:

  • Overcurrent and earth fault protection (single and four pole), with optional directional elements
  • Compact size (E4 case – 177 mm high (4U), 104 mm wide)
  • 3 or 6 BI, 5 or 8 BO, 10 tri-colour annunciator LEDs
  • DNP 3.0 Serial output (2 wire RS-485). 103 and Modbus RTU also supported
  • USB front interface
  • 24-80 Vdc or 80-250 Vdc auxiliary supply
  • Free setting software (Reydisp Evolution 32)
  • All the normal monitoring functions plus positive, negative and zero sequence values
  • Fault record storage for 10 events
  • Optional Auto reclose

Protection functions include undervoltage, undercurrent, broken conductor, negative phase sequence, thermal overload, earth fault and sensitive earth fault, CB failure, overvoltage, neutral displacement, high impedance earth fault, directional elements, cold load, CT and VT supervision, trip circuit supervision and lockout.

Solkor

The Solkor R/Rf is a very traditional and reliable approach to differential line protection operating over copper pilot wires. Solkor relays are well known and proven for their simple yet practical protection. Installation is simplified with no need for auxiliary supply circuits. Intertripping and pilot wire supervision products also available. For more complex protection requirements, we recommend the Siemens SIPROTEC 7SD600/610 series.

Test blocks

The range of 2RMLG test blocks, housed within an Epsilon enclosure, offers facilities for monitoring and secondary injection testing of power system protection schemes in conjunction with the MMLB 01 multi-fingered test plug.
