  • Page 37: 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 REF610 or as a station-wide arc protection including several REF610 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 38: 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 REF610 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 39 1MRS755535 Feeder Protection Relay REF610 REF610 Technical Reference Manual - ANSI Version The initiation of one or several auto-reclose shots can be set to be blocked by trip signals from certain protection elements. Blocking is also possible via a digital input.
  • Page 40 Feeder Protection Relay REF610 REF610 1MRS755535 Technical Reference Manual - ANSI Version set dead time for shot 3 will start. When the set dead time elapses, the blocking of selected protection elements (the same as for shot 2) will be activated and the AR function will issue a reclosing command to the circuit breaker.
  • Page 41 1MRS755535 Feeder Protection Relay REF610 REF610 Technical Reference Manual - ANSI Version Shot initiation by a pickup signal applies only to shot 1 and definite tripping. The AR function will issue an opening command to the circuit breaker at shot initiation by a pickup or a trip signal.
  • Page 42 Feeder Protection Relay REF610 REF610 1MRS755535 Technical Reference Manual - ANSI Version Activation of any above-mentioned signal will always cause the AR function to issue an opening command to the circuit breaker. If the signal used for blocking is not simultaneously used for initiation of the next shot, the AR function will generate a definite trip alarm and be locked out.
  • Page 43 1MRS755535 Feeder Protection Relay REF610 REF610 Technical Reference Manual - ANSI Version Information on the circuit-breaker position The AR function requires information on the circuit-breaker position. Any digital input can be selected for the information on the circuit breaker being open (CB Position Open) and closed (CB Position Closed) in SGB.

    1MRS755535 Feeder Protection Relay REF610 REF610 Technical Reference Manual - ANSI Version Application examples 6.1. Auto-reclose function 6.1.1. Fast tripping and initiation of shot 1 using two protection elements In several applications, such as fuse-saving applications involving down-stream fuses, tripping and initiation of shot 1 should be fast (instantaneous or short-time delayed) and of shot 2 and 3, and definite tripping time delayed.

  • Page 158: Pickup Signals

    An alternative way to achieve fast tripping and shot initiation (typical for certain countries, such as Finland), is to use pickup signals from protection elements for shot initiation. The AR function of REF610 can be initiated by the pickup signals from elements 51P and 51N.

    1MRS755535 Feeder Protection Relay REF610 REF610 Technical Reference Manual - ANSI Version At the factory default delay of 300 s for AR 51P pickup Delay and AR 51N pickup Delay, the pickup signals will, in practise, not be used for shot initiation. However, if elements 51P or 51N have been given an IDMT characteristic, the factory default delay of 300 s will function as a trip time limiter.
