Both Sides Grounded Testing On GIS Setup

Power on the ACTAS Px60.

Select the Test tile on the touch screen to create a new job.

ACTAS Px60 start screen with the Test tile — Select the Test tile.

Select New switchgear to create a new template.

In the upper-right corner of the screen, press the + icon to create a new template.

Switchgear template list with the plus icon in the upper-right corner — Use the plus icon to add a template.

Specify the switchgear manufacturer and model.

New template screen with switchgear manufacturer and model fields — Enter manufacturer and model details.

Select the Connections tab, then select the + button.

Select the Timing check box. Also select Drive to include the motor test, if required.
Select OK.

Connections tab with the plus button for adding a connection test — Add a connection test.

Test selection dialog with Timing and optional Drive check boxes — Select Timing and, if required, Drive.

Select Timing under the custom list.

Select Main contacts and set Test mode to PROMET.

Custom test list with Timing selected — Select Timing from the custom list.

Main contacts configuration with Test mode set to PROMET — Set the main-contact test mode to PROMET.

Select the Sensors tab and edit each sensor to I mc for A, B, and C. Select the gear symbol; the Rogowski coils can be selected from the library or configured directly to 100 mV/1 A.

While under Connections, configure additional criteria as required. Refer to step 9 in the general ACTAS Px60 Quick Start Guide.

Sensors tab showing I mc sensor assignments for phases A, B, and C and Rogowski coil settings — Configure the phase sensors and Rogowski coils.

SRM/DRM Testing

Press the back arrow at the top-left of the screen to go back.

Select the + button once more.
Select the Contact resistance check box.
Select OK.
Select Contact resistance under the custom list.
Select Configure. You must be connected to the PROMETS.
Select the hourglass button and set lead time to 5 seconds. Assign the PROMETS to their designated phases.
Select OK.
Select the X button to close the PROMET configuration.
Press the back arrow at the top-left of the screen to go back.

Custom test list with Contact resistance selected — Select Contact resistance from the custom list.

Contact resistance main-contact screen with the Configure option for connected PROMETS — Open PROMET configuration.

PROMET configuration showing five-second lead time and phase assignments — Set lead time and assign each PROMET phase.

Select the Sensors tab and edit each sensor to I mc for A, B, and C. Select the gear symbol; the AC/DC Current Clamp can be selected from the library or configured directly to 100 mV/1 A.

Sensors tab showing I mc phase assignments and AC/DC current clamp configuration — Configure the AC/DC current clamps for all phases.

Select the Analysis tab, then select Main contacts.

Select the Dyn Timing tab and set Calculation mode to Test current (Rogowski).
Press the back arrow at the top-left of the screen. While under Analysis, configure additional criteria as required. Refer to steps 7 & 8 in the general ACTAS Px60 Quick Start Guide.
Press the back arrow at the top-left of the screen.

Dyn Timing analysis settings with Calculation mode set to Test current (Rogowski) — Set the dynamic timing calculation mode.

Select the Tests tab, then select the Contact resistance tab.

Under the SRM tab, set Record duration to 3000 ms.
Press the back arrow at the top-left of the screen. While under Tests, configure additional criteria as required. Refer to step 6 in the general ACTAS Px60 Quick Start Guide.
Select the Save icon in the top-right corner to save.
Press the back arrow at the top-left of the screen to return to the list of switchgear templates, which will now include the template just created.

SRM contact-resistance settings with record duration set to 3000 milliseconds — Set the SRM record duration.

Select the template from the list to begin testing.

Switchgear template list containing the newly created template — Select the saved template.

Once the template has been selected, tests may now be performed.

Press the save button at the bottom-left of the screen.
To save the job, the fields marked with an * must be completed.

ACTAS Px60 test monitor after selecting the configured template — Perform tests from the test monitor.

Job save screen with required fields marked by an asterisk — Complete the required fields to save the job.

When switching between Timing and Contact Resistance (SRM & DRM), the Rogowski coils and AC/DC current clamps must be interchanged.

For Timing, note the direction of the arrow on the Rogowski coil; it should point in the direction of current flow. Once Timing is complete, remove the Rogowski coils from the GIS and install the AC/DC Current Clamps on the insulated earthing switch. On some GIS types, the clamp may not fit.

Setup complete. The GIS template is configured for both-sides-grounded timing and SRM/DRM contact-resistance testing, and can be selected to perform and save tests.
