Figure 41 Run All Test Screen
In order for the MVCT to estimate the performance of the VT, the MVCT must have the Advanced VT
package installed and each test outlined in the Run All test screen must be performed on the VT. In the
Basic VT testing the Saturation Test and Short Circuit Impedance Test are not available. The user can
easily configure a test plan for a voltage transformer by checking the box adjacent to the desired test.
The MVCT will then cycle through and perform each test. Please note though that a lead change may be
required after completion of one test and before beginning of the next test. The MVCT will alert the
user as to the proper connections for the upcoming test prior to the test beginning. Please closely
evaluate each connection diagram and ensure the unit is properly connected before continuing.
** Please note that both proper and improper connections during a test can result in an
extremely dangerous environment being generated. The user should carefully read all safety
precautions and understand them prior to beginning any testing. The user should also follow all
connections diagrams and read the warnings on such in order to be aware of the environment.
The various buttons at the bottom of the screen can also be used to easily configure a test:
