NOTE
: If 59 #1 and 59 #2 have different pickup settings, it would be efficient to disable the one with the
lower setting first and test the higher setting operation. The lower setting operation could then be
tested without disabling the higher setting.
1.
Disable functions as shown. See Section 3.2, Setpoints and Time Settings, for procedure.
2.
Confirm settings to be tested.
3.
Connect inputs in Configuration V1 designated above. See Section 5.1, Equipment /Test Setup
for configuration. Set Voltages = Nominal Voltage (see Table A-3, System Setup Record Form).
4.
Pickup Test
: Press and hold the
TARGET/OUTPUT RESET
pushbutton and slowly increase the
input voltage on phase A until
59/59I PHASE OV
LED illuminates or the pickup indicator operates
on the Status Function screen. The level should be equal to
P
&
0.5 V or
&
0.5%. Release the
TARGET/OUTPUT RESET
pushbutton and decrease the input voltage to nominal voltage. Press
TARGET/OUTPUT RESET
pushbutton to remove targets.
5.
Time Test
: With output contacts (
Z
) connected to stop the timer, apply (
P
+5) % on phase A and
start timing. The contacts will close after
D
cycles 20 cycles (RMS) or
&
2 cycles (DFT).
6.
Test phases B and C (or AB and BC for Line-Line VT configurations) by repeating steps 4 and 5.
7.
If testing is complete, enable any functions disabled for this test. If other tests are to be
completed, check the proper functions to disable for the next test and proceed from this point.
