The IEC 61850 communication implementation supports

monitoring and control functions. Additionally, parameter

settings, disturbance recordings and fault records can be

accessed using the IEC 61850 protocol. Disturbance

recordings are available to any Ethernet-based application in

the standard COMTRADE file format. The relay supports

simultaneous event reporting to five different clients on the

station bus.

The relay can send binary and analog signals to other devices

using the IEC 61850-8-1 GOOSE (Generic Object Oriented

Substation Event) profile. Binary GOOSE messaging can, for

example, be used for protection and interlocking-based

protection schemes. The relay meets the GOOSE performance

requirements for tripping applications in distribution

substations, as defined by the IEC 61850 standard (class P1.

<3 ms data exchange between the devices). The relay also

supports the sending and receiving of analog values using

GOOSE messaging. Analog GOOSE messaging enables easy

transfer of analog measurement values over the station bus,

thus facilitating, for example, the sending of measurement

values between the relays when controlling transformers

running in parallel.
