Overview
RED615 is a two terminal phase segregated line differential protection IED designed
for the protection, measurement and supervision of feeders in utility substations and
industrial power systems. Re-engineered from the ground up, the IED has been guided
by the IEC 61850 standard for communication and interoperability of substation
automation devices.
The IED provides unit type main protection for overhead lines and cable feeders in
distribution networks. The IED also features current-based protection functions for
remote back-up to the down stream protection relays and local back-up for the line
differential main protection.
The IED is adapted for the protection of overhead line and cable feeders in isolated
neutral, resistance earthed, compensated (impedance earthed) and solidly earthed
networks. Once the standard configuration IED has been given the application-
specific settings, it can directly be put into service.
The 615 series IEDs support a range of communication protocols including IEC
61850 with GOOSE messaging and Modbus®.
