Instructions for the installation and

commissioning of Power Xpert

 

IGX

medium-voltage switchgear

Section 4:  Installation

 

WARNING

BEFORE PLACING THE POWER XPERT IGX SWITCHGEAR IN SERVICE, 

CAREFULLY FOLLOW THE INSTALLATION PROCEDURE GIVEN BELOW. NOT 

FOLLOWING THE PROCEDURE CAN FAIL TO UNCOVER SHIPPING DAMAGE 

THAT MAY RESULT IN INCORRECT UNIT OPERATION LEADING TO DEATH, 

BODILY INJURY, AND EQUIPMENT DAMAGE. 

Before installing Power Xpert IGX, a careful check should be made to 

ensure that all packaging materials have been removed.

ote: 

N

To ensure a satisfactory installation sequence and quality, Power Xpert 

IGX switchgear vertical sections’ installation should be performed under 

the supervision of trained and qualified field engineers.

4.1.  Qualified personnel

 

WARNING

IMPROPERLY INSTALLING OR MAINTAINING THESE PRODUCTS CAN 

RESULT IN DEATH, SERIOUS PERSONAL INJURY, OR PROPERTY DAMAGE. 

 

READ AND UNDERSTAND THESE INSTRUCTIONS BEFORE ATTEMPTING 

ANY UNPACKING, ASSEMBLY, OPERATION OR MAINTENANCE OF THE 

EQUIPMENT.  

 

INSTALLATION OR MAINTENANCE SHOULD BE ATTEMPTED ONLY 

BY QUALIFIED PERSONNEL. THIS INSTRUCTION BOOK SHOULD NOT 

BE CONSIDERED ALL INCLUSIVE REGARDING INSTALLATION OR 

MAINTENANCE PROCEDURES. IF FURTHER INFORMATION IS REQUIRED, 

YOU SHOULD CONTACT EATON.

4.2.  Tool and hardware requirements

Metric tools and hardware are required for this installation.

4.3.  Initial inspection before setting in place

Power Xpert IGX vertical sections will arrive in shipping groups 

of one or more sections. Shipping group vertical sections will be 

electrically and mechanically connected, so that only attachments 

and connections between shipping groups will be necessary during 

installation.
See sections 

4.7. Anchoring shipping groups to the foundation 

and 

4.10. Bolting adjacent shipping groups 

for details on 

placement and attachment of shipping groups. As each shipping 

group is attached to the previously-installed group, it will require 

electrical connection to the group main bus links and ground bus. 

See section 

4.8. Installing main bus and coupling the units 

for 

details on connecting main bus links to adjacent shipping groups.

ote: 

N

Once a vertical section or shipping is in place, record the tank 

gas pressure gauge readings on each switchgear unit. This will 

be compared with gas pressure readings prior to energization to 

determine if any gas leaks have occurred.

Electrical and mechanical checks
Each vertical section will have a 3PS Mech and/or VT 3PS Mech 

manual operation panel on the front of the enclosure. This panel 

will have either one switch control (3PS Mech only) or two switch 

controls (when both 3PS Mech and VT 3PS Mech are supplied). The 

Three Position Switch (3PS) should be checked both mechanically 

and electrically. The Voltage Transformer Three Position Switch (VT 

3PS) does not have a motor and will only be checked mechanically.
Mechanical checks
The 3PS Mech and VT 3PS Mech (if furnished) control(s) should 

show their switches in the grounded positions when received. See 

Figure 11.

Interlocking
The 3PS Mech and circuit breaker are interlocked to prevent 

inappropriate operation. Refer to the project schematics and 3PS 

Mech controller program for details. In summary,

• 

The 3PS Mech cannot operate, either electrically or 

mechanically, if the CB is closed.

• 

The 3PS Mech manual operation blocking plates cannot be 

opened if the CB is closed.

• 

The 3PS Mech cannot be electrically operated while the 

Manual Operation T-Handle is inserted in either port.

• 

A solenoid prevents 3PS Mech manual operations if control 

power is absent.

• 

The CB cannot be electrically operated while the manual 

operation T-Handle is inserted in either port.

• 

The CB (if open) cannot be closed if either 3PS Mech manual 

operation blocking plate is open.

4.3.1.  3PS Mech manual operation

Under normal circumstances, a 3PS is operated electrically, with 

local or remote operator devices controlling an electric motor drive. 

If the electric drive is not available, a manual, mechanical means 

for operating the 3PS can be used. The following describes these 

mechanical features and their use.
Local permissive/control devices
The 3PS Mech Manual Operation Module has devices that 

mechanically permit or prohibit operation of the 3PS Mech (see 

Figure 11

). These devices are Keylock/Padlock plungers for 

• 

Lock Connect (standard)

• 

Prevent Connect (optional)

• 

Lock Ground (standard)

• 

Prevent Ground (optional)

These devices mechanically set conditions for the 3PS, for both 

electrical and manual operation. When a Keylock/Padlock plunger 

is depressed into the manual control module and locked in place 

either with its keylock or a padlock inserted through the plunger and 

bracket holes, it sets the operating mode for the 3PS: Switch Locked 

Connect, Switch Prevented from connecting to the circuit breaker, 

Ground Switch Locked grounded, or Ground Switch prevented from 

connecting to ground.
The 3PS and VT 3PS require control power to operate.
The 3PS Mech and VT 3PS Mech (if furnished) can be operated 

manually using the appropriate switch mechanism mounted on the 

front of the vertical section. Each switch has three operating states: 

Connect, Disconnect and Ground.
Performing manual operations requires two tools:

• 

Manual Operation T-Handle (

• 

Access Selector Key (
