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

.
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.
