Testing and Troubleshooting
Acceptance Testing
Step 4. Purpose: Repeat test for each instantaneous overcurrent
element for each winding.
Method:
a. Repeat Step 1 through Step 3 for each instantaneous
overcurrent element listed in Table 10.1 for each
winding.
b. Remember to view the appropriate TARget and apply
current to the appropriate winding. The computer
terminal will display the LED labels from left to right
when the TAR F command is issued.
