1.1.1
Non-Pilot Performance Tests
To prepare the REL300 relay assembly for Non-Pilot Acceptance Tests, connect the REL300
per Figure B-1, Configuration 1(page B-6).

NOTE:
Be sure that the RP setting is "NO". If the RP setting is "YES", the readings will be the
primary side values.
The angle measurement is for reference only. For I<0.5A, the display of angle will be
blocked and show zero degrees.

Zone 1 Test/Single-Phase-To-Ground
Step 10. (a)

Turn on rated battery voltage. Check the FREQ setting to match the line frequency
and ct type CTYP. Apply a balanced 3-phase voltage (70 Vac); the Alarm-1 relay
should be energized. (Terminals TB4-7 and -8 should be zero ohms.)
Check "RELAY-IN-SERVICE" LED; it should be "ON".
Press "RESET TARGETS" push-button; the green LED (Volts/Amps/Angle) should
be "ON".
Press the DISPLAY SELECT pushbutton, and note that the mode LED cycles thru
the five display modes. Release the pushbutton so that the SETTINGS mode LED
is "ON".
Refer to Section 4 (Installation Section, Table 4-1), for all possible REL300 SET-
TINGS, and set the values in accordance with Table A-1. For Negative Sequence
Directional Unit, change DIRU from ZSEQ to NSEQ. For dual polarizing directional
ground unit, change DIRU to DUAL.
Press the DISPLAY SELECT pushbutton to obtain the METERING mode (VOLTS/
AMPS/ANGLE). (Refer to Table 4-2, page 4-19)
Using Figure B-1, Configuration 1, apply three ac voltages of 70 V
rent of 1A. Adjust phase A current to lag phase A voltage (V
