5.3 ZONE REACH AND TIMER TESTS
5.3.1 GENERAL ZONE REACH TESTING CONSIDERATIONS
1.
The Zone measuring units are checked in the test mode of operation. The A1 (programmable alarm) con-
tact indicates when the unit has operated. It is the only measure of whether the test passes or fails. The
displayed target information is for reference only. Different test equipment methods can alter the output
from what is shown.
The display output is shown for reference only; it is not part of the test. The display includes the target
information.
2.
When a particular zone is under test, the other protection zones are disabled so that they do not time out
and distort the results of the zone under test.
The backup protection functions will cause the relay to trip during zone testing, as they should. They must
be disabled to isolate the zone reach unit under test. Before doing any of the reach tests make the follow-
ing protection settings changes:
OVERCUR
(601)
50 = NO
(605)
50G = NO
(610)
51G = NO
OS BLOCKING
(1603) BLOCKWHAT = 3 (BLKNONE)
After the zone reach testing is completed, restore these settings to their pretest values.
