WARNING

POWER DISTRIBUTION AND TRANSMISSION EQUIPMENT MUST BE

PROPERLY SELECTED FOR THE INTENDED APPLICATION. IT MUST BE

INSTALLED AND SERVICED BY COMPETENT PERSONNEL WHO HAVE BEEN

TRAINED AND UNDERSTAND PROPER SAFETY PROCEDURES.

THESE INSTRUCTIONS ARE WRITTEN FOR SUCH PERSONNEL AND

ARE NOT A SUBSTITUTE FOR ADEQUATE TRAINING AND EXPERIENCE

IN SAFETY PROCEDURES. FAILURE TO PROPERLY SELECT, INSTALL OR

MAINTAIN POWER DISTRIBUTION AND TRANSMISSION EQUIPMENT

CAN RESULT IN DEATH, SEVERE PERSONAL INJURY, AND EQUIPMENT

DAMAGE.

DANGER

ALL ASSOCIATED APPARATUS MUST BE DE-ENERGIZED DURING ANY

HANDS-ON INSTALLATION OR MAINTENANCE. FAILURE TO COMPLY WILL

RESULT IN DEATH, SEVERE PERSONAL INJURY AND EQUIPMENT DAMAGE.

Cable cleats
All cables terminated at the XGIS cable bushing must be secured

with cable cleats. Detailed installation instructions for cable cleats

can be found in Eaton Cooper installation manual CTCC-10.
See

Figure 24

for an example of cable cleats.

CAUTION

IMPROPERLY SUPPORTED CABLE CONNECTORS COULD RESULT IN

PERSONAL INJURY OR EQUIPMENT DAMAGE. THE APPARATUS BUSHING

AND TEE CONNECTOR SHOULD NOT SUPPORT THE WEIGHT OF THE CABLE

AND ARRESTER. CLAMP THE CABLE IMMEDIATELY BELOW THE CABLE

JACKET SEAL, AND SUPPORT THE ARRESTER BELOW THE LOWER OF

ARRESTER’S STEP. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD

LEAD TO SHORT CIRCUIT OR ARCING EVENT.

5.13 Installing current transformers

DANGER

ALL ASSOCIATED APPARATUS MUST BE DE-ENERGIZED DURING ANY

HANDS-ON INSTALLATION OR MAINTENANCE. FAILURE TO COMPLY WILL

RESULT IN DEATH, SEVERE PERSONAL INJURY AND EQUIPMENT DAMAGE.

XGIS current transformers are installed in the factory prior to

shipment but may be removed or changed in the field after the

vertical sections have been aligned and attached.
The CTs are held in place by brackets attached to the vertical section

surfaces. The hardware to be applied on the CTs will vary depending

on the CT type, rating, applicable standards, quantity and location.

The brackets to be applied and the mounting hardware to be used

are specified on the project installation drawings.

5.13.1 Main bus compartment CTs

Main bus CTs are mounted on top of the tank, using brackets

designed for the purpose. There are a variety of main bus CT bracket

designs, depending on which CTs are to be installed.
In every case, the CTs will be installed on the tank top before the

SSIS bus and bus joints are installed.

Figure 34

shows how the main bus CTs encircle the SSIS busbar.

They are held in place by mounting brackets appropriate for the CT

rating and applicable standard.

Main bus CTs are attached to the main bus compartment top

surface using brackets and mounting hardware.

Figure 35

shows the

details of the CT mounting brackets for both XGIS design ranges.
CT examples

Figure 36

and

Figure 37

are examples of main bus side CTs, for

1250 A and 2000 A / 2500 A, respectively.

Figure 38

shows the main bus CT brackets for 1250 A and 2500 A

ratings.

5.13.2 Cable side CTs

Cable side CTs are also held in place using mounting brackets. There

are two possible ways to connect the cable compartment output

bushings: using cable connections or using bus connections.
