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

Argus-MThe Argus-M is similar to the Argus-C, but significantly offers a larger I/O count and in addition to DNP support, it also offers an IEC 61850 Ethernet interface option. |

SolkorThe 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 7SD80. |

Solkor-NThe Solkor-N is a differential protection relay for use with copper or fibre pilots. It includes pilot supervision, backup over current protection and IEC 103 or MODBUS RTU SCADA interface. |
