Standardized communication

As a standard feature, REF615R supports the IEC 61850

standard for inter-device communication in substations along

with the industry standards DNP 3.0 and Modbus protocols.

The implementation of the IEC 61850 substation communi

cation standard in REF615R encompasses both vertical and

horizontal communication, including GOOSE messaging and

parameter setting according to IEC 61850-8-1. The substation

configuration language enables the use of engineering tools for

automated configuration, commissioning, and maintenance of

substation devices.

The REF615R integrates basic control functionality, which

facilitates the control of one circuit breaker via the relay’s front

panel human machine interface (HMI) or remote control system.

To protect the relay from unauthorized access and to maintain

the integrity of information, the relay has been provided with a

four-level, role-based user authentication system, with individual

passwords for the viewer, operator, engineer, and administra

tor levels
