M‑3311A Instruction Book
6–28
Standard Curve Testing
: The operating time will be read from Appendix D, Negative Sequence
Inverse Time Curves for the applied current and appropriate Time Dial (
TD
) setting. The curve
portions extending to lower than
P
current values are inactive and can be ignored.
t = time in seconds TD = Time Dial setting M = current in multiples of pickup
5.
Time Test
: With output contacts connected to the timer, apply currents equal to the multiple of
the Inverse Time Pickup (
P
) and start timing. The operating time will be as calculated in Step 4,
3 cycles or
5%. Observe
46DT/IT NEG SEQ O/C
(46 DT/IT NEG SEQ O/C) LED for pickup.
6.
If further testing is desired, check the proper functions to disable for the next test and continue
from this configuration.
7.
Repeat steps 3, 4 and 5 for Winding 3 and Winding 4.
8.
If testing is complete, enable any functions disabled for this test.
