AC Voltage and
Current Input
Test
Testing AC Analog Inputs: Changes are displayed in WESMAINT.
Procedure: Test
AC Voltage and
Current Input
To conduct this test, the code and configuration file must be downloaded to
the D25’s FLASH memory.
Note
: The actual point descriptions displayed in WESMAINT depend on
the circuit configuration (i.e., line-to-line or line-to-neutral, etc.) and
any changes made to the point descriptions in the running
configuration file.
To verify that the correct AC voltage and current values are displayed in
WESMAINT:
Step Action
1 Navigate to the WESMAINT II+ System Data Menu.
2 On the System Data Menu , type 3 — Analog Input Display .
PT input test
3 Press the down arrow key to scroll to the point named RMS
Voltage Phase A Circuit 1
. (see Note: above)
4 Apply nominal voltage to the first AC voltage input termination
points.
5 Verify that the measured counts are close to their nominal value.
6 Go back to Step 3 and repeat for other points on the AC voltage
(PT) input termination.
CT input test
7 When voltage input tests are complete, press the down arrow key
to scroll to the point named RMS Current Phase A Circuit 1
8 Apply nominal current to the first AC current input termination
points.
9 Verify that the measured counts are close to their nominal value.
10 Go back to Step 7 and repeat for other points on the AC current
(CT) input termination.
