Appendix A - XGIS switchgear commissioning checklist
This section is intended to be an informal reference only and
covers recommended XGIS switchgear commissioning practices.
It is ultimately the responsibility of the commissioning contractor
to determine the level of activities required to satisfy the project
requirements on an application by application basis.
Initial conditions
Confirm that there are no SF
6
pressure alarms present.
Confirm all supply voltages are available. Switch off and lock
out all supply voltages.
Examine the equipment installation:
All panels are installed and anchored to the floor
All panels are the correct distance from the walls
All panels are leveled to specification and main bus cone
separation distances are correct
All insulating surfaces are clean and dry
All compartments are free of loose parts, tools, litter and
miscellaneous construction items
All barriers and covers are in place and secured
All warning signs and labels are in place
Touch up any surface damage to doors, panels, etc.
Inspections
Verify gas pressure 1.3 bar/ green on gauge
Inspect burst disk (overpressure relief device) if accessible.
Verify position of 3 position ground/open/closed switch
Verify VT Earthing Switch operation
Verify VT Earthing Switch is engaged and locked
Verify all interconnects
Verify camera installation (optional)
Verify CTs connections to shorting blocks
Verify PTs connections to terminal blocks
Control power OFF mechanical testing (for each XGIS vertical
section)
Confirm control power is switched off and locked out;
Start with the CB Open
Manually charge the CB spring
Attempt to Close the CB; CB should not close with control
power off (magnet pin must be defeated)
Confirm that the 3PDS Manual Access door will open with the
CB open (due to the mechanical linkage)
Use the 3PDS Manual Operation T-handle to move the 3PDS
to Ground, Open and Closed positions as indicated by the
3PDS Status flags on the operator front panel; Confirm the
detent stop at each position. The T-handle will require removal
and re-insertion after arriving at each position.
Return the 3PDS to Open position; close the Manual Access
Door
Control power ON mechanical testing (for each XGIS vertical
section)
The CB is open; the 3PDS is open; the 3PDS manual door is
closed; no medium voltage is present on the cable side
Apply control power; the CB charging motor will charge the
spring if not already charged; the CB charging motor will stop
once charging is complete. The Mechanism Status window
(viewable through the vertical section door cutout) will show
“Charged.”
Open the vertical section low voltage control panel door. Close
and Open the CB using the mechanical buttons on the CB
front panel. The vertical section low voltage control panel door
CB status indicating lights will illuminate as appropriate.
Control power ON electrical testing - local to each vertical
section
With the CB open, open the 3PDS Manual Access Door.
Confirm that closing the CB using the panel door pushbutton
is not permitted. Confirm that 3PDS panel door pushbutton
operations are not permitted. Close the 3PDS Manual Access
Door.
Close the 3PDS using the panel door pushbutton, confirm
that CB electrical operations using panel door pushbuttons
are permitted (when 3PDS is in Closed position). Confirm that
panel door 3PDS Closed indicating light is illuminated.
Open the CB if not already open. Open the 3PDS using
panel door pushbutton. Confirm that the panel door 3PDS
Open indicating light is illuminated. Confirm that CB electrical
operations (using panel door pushbuttons) are permitted
(when 3PDS is in the Open position)
Open the CB if not already open. Ground the 3PDS using
the panel door pushbutton. Confirm that the panel door
3PDS Grounded indicating light is illuminated. Confirm that
CB electrical operations (using panel door pushbuttons) are
permitted (when the 3PDS is in Ground position and no
voltage is present on the cable side).
Close the CB using panel door pushbutton. Attempt to close
the 3PDS using panel door pushbutton. Confirm that closing
the 3PDS is not permitted with the CB closed.
Control Power On Electrical testing - remote
If the project includes remote control of the CB, confirm the
above Power On CB tests using remote contact closures in
place of panel door pushbuttons
If the project includes remote indication of CB and 3PDS
status, confirm that the appropriate indication occurs with CB
and 3PDS operations.
