Test Methods
Step 7. Connect a test source to the relay.
a. Set the current output of a test source to zero output level.
b. Connect a single-phase current output of the test source to the
IAW analog input.
Step 8. Test the element.
a. Increase the current source to produce a current magnitude of
1.125 A secondary in the relay.
b. Keep the current source at this level past the expected element
time-out (longer than 3.2 seconds).
c. Return the current source to zero after the element times out.
Step 9. Select the HMI menu (top toolbar) to start the QuickSet HMI interface.
Step 10. View the SER report. Click the SER button of the HMI tree view.
QuickSet displays the SER report similar to Figure 10.7.
The time difference between SER entries 51S1 PICKED UP and
51S1 TIMEOUT is approximately 3.2 seconds.
