  • Page 34: Arc Protection

    Local light detection requires the optional arc light detection hardware. The arc protection can be realized as a stand-alone function in a single REF 610 or as a station-wide arc protection including several REF 610 protection relays. If realized as a station-wide arc protection, different tripping schemes can be selected for the operation of the circuit breakers of the incoming and outgoing feeders.

  • Page 35: Auto-Reclose Function

    At a permanent fault, auto-reclosing is followed by definite tripping. A permanent fault must be located and cleared before the fault location can be re-energized. The auto-reclose (AR) function of REF 610 can be used with any circuit breaker suitable for auto-reclosing. The AR function provides three programmable auto- reclose shots and can thus be set to perform one to three successive auto-reclosures of desired type and duration, one high-speed and one delayed, for instance.
  • Page 36 Feeder Protection Relay REF 610 REF 610 1MRS755310 Technical Reference Manual The AR function monitors the position and status of the circuit breaker. Information on the circuit-breaker position is always required whereas circuit-breaker status is optional. For safety reasons, shot initiation is not possible when the circuit breaker is open.
  • Page 37 1MRS755310 Feeder Protection Relay REF 610 REF 610 Technical Reference Manual If the network fault has still not been cleared, i.e. all selected auto-reclose shots have been unsuccessful, and the protection trips the circuit breaker before expiration of the set reclaim time, the AR function will generate a definite trip alarm. The circuit breaker will now remain open and the AR function will be locked out.

  • Page 156: Arc Protection

    An arc protection with one REF 610 only (see Fig. 6.2.1.-1) is realized by installing two arc lens sensors, connected to the relay protecting the incoming feeder, to detect an arc on the busbar.

    6.2.2. Arc protection with several REF 610 relays When using several REF 610 relays (see Fig. 6.2.2.-1), a REF 610 protecting an outgoing feeder will trip the circuit breaker of the outgoing feeder when detecting an arc at the cable terminations. If the REF 610 protecting the outgoing feeder detects an arc on the busbar (via the other lens sensor), however, it will generate a signal to the REF 610 protecting the incoming feeder.
