ABB REF615R Feeder protection and control Communication

Pre-emptive condition monitoring

For continuous knowledge of the operational availability of the

REF615R features, a comprehensive set of monitoring func

tions to supervise the relay health, the trip circuit, and the circuit

breaker health is included. The breaker monitoring can include

checking the wear and tear of the circuit breaker, the spring

charging time of the breaker operating mechanism and the gas

pressure of the breaker chambers. The relay also monitors the

breaker travel time and the number of circuit breaker operations

to provide basic information for scheduling breaker mainte nance.

Bus protection via GOOSE

The IEC 61850 implementation in REF615R includes

fast peer-to-peer communication, over the substation bus.

Use GOOSE communication between REF615R IEDs of the

incoming and outgoing feeders of a substation to form a stable,

reliable, and high-speed busbar protection system. The cost-ef

fective GOOSE-based busbar protection is obtained by config

uring the IEDs and the operational availability of the protection

is assured by continuous supervision of the protection IEDs

and their GOOSE messaging over the station bus. No separate

hard-wiring is needed for the horizontal communication between

the switchgear cubicles.
