1.1.4 REL300 WITH OUT-OF-STEP BLOCK OPTION
Refer to Figure B-5, page B-10. The RT setting (21BI) is for the inner blinder and it is also used
for three-phase fault load restriction. The RU setting (21BO) is for the outer blinder. If the setting
of OSB is "YES", and the power swing stays inside the two parallel lines (RT and RU) for more
than 50 ms, the three-phase fault trip will be blocked until the timer (OSOT) times out.
Connect the test circuit as shown in Figure B-2 (page B-7).
A-20
Turn V "OFF"; the relay should trip with a target of WFT, and the Carrier Send
an
contact (TB4-1 and TB4-2) should close momentarily.
Apply a balanced 3-phase 70 Vrms and apply a reverse AG fault current of 5A (i.e.,
I leads V by 105 degrees). Turn V
a an
Carrier Send contact (TB4-1 and TB4-2) should stay open.
This completes the basic Acceptance Test for the REL300 Pilot System. (See sub-
sequent segments for optional Single Pole Trip test.)
Set relay per Table A-1(page A-27. Check the 62T setting; it should be 5.000. For
a Pilot System, change the setting to PLT = YES, and apply a rated dc voltage to
Pilot Enable terminals TB5/9(+) and TB5/10(-). Also apply a rated voltage to RCVR
#1 terminals TB5/7(+) and TB5/8(-) if the STYP = POTT or PUTT; set TTYP = SPR.
Apply AG fault as shown in this Appendix Section 1.1.1.3, Step 10 (page A-2)The
Trip A contacts (2FT-14/1-2 and 3-4) should be closed. Repeat BG fault (for Trip B
contact closures) and repeat CG-Fault (for Trip C contact closures).
Apply a rated dc voltage to 52a terminals TB5/1(+) and TB5/2(-) and to 52b termi-
nals TB5/3(+) and TB5/4(-). Connect a Westinghouse Lockout (WL) switch to the
trip circuit.
Apply a phase-to-phase fault (as shown in this Appendix, segment 1.1.1.5, Step
13, page A-5). Turn the fault current "ON" and "OFF". The WL switch trips with a
target of SPF.
Set the WL switch, immediately; it will trip again with a target of 62T. Remove the
voltages from 52a and 52b.
Refer to the Non-Pilot Performance Tests section 1.1.1 (page A-2) for the single-
phase-to-ground faults (Steps 10 and 11), and to the three-phase fault (Step 12).
The fault current should be 20% greater than the calculated values for the tests in
these steps. The "fault types" applied to the REL300 relay are shown in Table A-3
(column 2). TTYP settings are shown in column 1, whereas the results of RI, Trip,
and BFI contacts are shown in columns 3, 4, and 5, respectively.
"OFF"; the relay should not trip, and the
