    Section 3 1MAC308145-MB E RER620 application loads. It provides a control capability function of the recloser to trip and/or lockout whenever there is a fault on one-phase, two-phases or three-phases. This feature allows an electric utility to prevent unnecessary three-phase interruptions and outages of their distribution network where a majority of outages can be attributed to single-phase transient type faults thereby improving the overall power system reliability and quantity of power delivered to customers on the distribution feeder.

  • Page 64: Opup Mode - Only Picked Up Phases

    Section 3 1MAC308145-MB E RER620 application • When a single phase has locked out, the reset timer will count down from its set value in the recloser settings. If another phase becomes involved before the reset time expires, that phase will operate one shot to lockout. If, alternatively, the reset timer has expired, the additional involved phase will go through the full sequence of programmed operations.

    Section 3 1MAC308145-MB E RER620 application In case of mid-point mode, the numbers of voltage transformers connected can be either 1 or 3. So the Vt config line can be either "1" or "3". The phase selection is similar as in sectionalizer mode but Vt config line cannot be "2".
