5.8.3. Creating a Test Plan for a Voltage Regulator

To create a test plan for a voltage regulator:

1. From the Test-Plan menu or the File menu, click on Create Test Plan, and then click on

Voltage Regulator. The following window will be displayed:

2. Enter the number of steps in the corresponding input box. This is the number of taps

above or below the neutral position of the voltage regulator. The test plan generated
will have this number of steps above and below neutral. The total number of steps will
be twice this number plus one (neutral).

3. Enter the fraction of 1% per step value in the corresponding input box. This defines how

each step voltage is raised or lowered. The value must be entered as a fraction.

4. Enter the H voltage at neutral. This is the high side voltage at neutral.

5. Select the voltage regulator tap location from the corresponding drop-down list. Select

“Low” if the voltage regulator taps are located on the low side of the transformer
winding. Select “High” if the voltage regulator taps are located on the high side of the
transformer winding.
