Page 312: Single Phase Tripping
Overview of the features in single-phase tripping As an example of single-phase operation of an RER620 with a recloser, imagine that the recloser is protecting a rural three-phase line. Suppose that a fault occurs on A-phase, where the fault is permanent and there is no fuse between the recloser and the fault.
Page 313 A. The RER620 will detect that fault and initiate a binary output signal from the RER620 to the recloser for pole A, the recloser will trip open phase A and then await timing from the RER620 for reclose or lockout. Comparable sequences may occur and operation of the RER620 will continue to operate for phase C or any combination of phase(s) caused by excessive load or fault current.
Page 314 OPUP mode. However, if a combination of two or three phases pickup or detect a fault, then the RER620 will initiate a binary trip output to the recloser for all three poles to trip.

Page 343: Sectionalizing Recloser
1MAC309294-MB F Control functions A recloser loop control scheme typically utilizes a predetermined RER620 controlled reclosers installed in series between two substation feeder circuits. This provides isolation of any faulted section within a given distribution circuit while re-establishing service to all customers unaffected by the faulted section within a relatively short period.
Page 344: Midpoint Recloser
The Midpoint recloser also is normally closed. Unlike the Sectionalizing recloser, however, it does not open in response to phase voltage loss. Instead, it supports loop control by automatically altering the RER620 settings in accordance with changing voltage conditions. Specifically, upon the expiration of it's under voltage timer, it will switch to a new setting group to prepare for a back feed condition and for a period will go into non-reclose mode.

Page 351 B proceeds through its reclosing sequence of overcurrent protection, which is the primary protection activity for the RER620. Upon tripping of recloser B, recloser T senses loss of voltage and after its time delay of t1 seconds, closes onto the permanent fault. Since this fault is permanent and recloser T has closed into the fault, recloser T goes directly to lockout by design.

Page 354 The Midpoint recloser C senses the same loss of voltage, and if the voltage does not return for the livebus timer setting will request the RER620 to start its SWOTF timer and, if programmed, to use new changed group settings after t2 seconds (typically set around 10 seconds after the Sectionalizer is set to lockout).

The main UPS function is to enable operation of the RER620 after the loss of control power for a period of time that depends on the amp hour rating of the battery. A 12 amp hour battery will power the total system for about 38 hours with a standard load.

Battery start The UPS has a function that will start the RER620-controlled recloser system if the battery is charged to a voltage of about 44 Vdc. In order to start the UPS using battery power, the power switch S1 must be pressed and held for about five seconds.
Page 434: Auxiliary Power Supply
The APS has two output voltage settings, 12 Vdc and 24 Vdc. The voltage selection is made by communications from the RER620. The supply may be switched on or off by communications as well. In applications where the supply is not needed, switching it off will extend the battery life.

9.1.3.6 RER620 power Power to the RER620 is provided by UPS connector W1 pins 7 (+60 Vdc) and 8 (return). This connection can provide about 30 watts. (In normal operation the RER620 will consume about 15 watts.) When the UPS is operating from battery power, the supplied voltage is the battery’s positive voltage.
