About the
Acceptance
Test Setting File
The acceptance test setting file provided is not necessarily configured to a pro-
vide a realistic setting example. Its configuration is intended to demonstrate
simple test methods for each relay element. Tests are organized to prevent in-
terference of one protection element on the next within the relay for ease of
testing without using multiple setting files and minimizing the number of test
connection changes. All contacts in the relay will be tested if all elements in
this procedure are tested as written.
Testing all the elements is accommodated by using of the relay Setting Groups
(3 groups are used).
Setting Group 1 tests elements: 21P, 21N, 68, 60, Switch On To Fault, Weak
Infeed
Setting Group 2 tests elements: 46-50/46-51, 50/51, 50N/51N, 27, 59, 50LS,
50BF
Setting Group 3 tests elements: 25/27/59 (Sync Check), 79, 81
The file demonstrates all types of impedance characteristics available in the re-
lay: circle, tomato, lens, Quadrilateral.
Virtual Inputs are used to perform some input functions and demonstrate their
use.
In addition to, or exclusive of these tests, the user may wish to perform dynam-
ic simulation tests on the relay to verify the relay operates as per protection
scheme design using the settings that are applied for the particular line on
which the relay will be installed.
