(GE) voltage regulator
application
The replacement procedure may be performed in the shop
or the field. The regulator must be bypassed or removed
from service prior to installing the CRA kit. Always bypass
the regulator when installing the CRA kit in the field to
prevent opening the CT circuit while the regulator is under
load.
Note: The control cable may be an actual cable or a flexible
conduit. For these instructions, it will be referred to as
"control cable".
1. Bypass the regulator or remove it from service.
2. Disconnect the GE position indicator plug assembly
from the bottom of the position indicator.
3. Open the existing control box and note the incoming
control cable leads and associated color-coding. If the
incoming control cable leads are not marked or color
coded, place appropriate wire markers on the control
cable leads and mark for reference later.
4. Disconnect the incoming control cable leads from the
terminal strip(s) located on the back of the GE control
box.
If the tap-changer motor capacitor is located in the
control box, disconnect the leads from the capacitor
and remove the capacitor for reinstallation in the CRA
control box.
5. Remove the incoming control cable-retaining nut and
remove the cable from the control box.
If the regulator is fitted with a non-flexible conduit
housing the control leads, it will be necessary to modify
or replace this conduit with a flexible conduit to allow
interface to the CRA control box.
6. Remove the cable compression connector (cable grip)
from the control box.
7. Remove the nameplate from the old control box
assembly and retain, with the hardware.
8. With an adjustable wrench (or appropriate socket
wrench), remove and retain the bolts holding the con-
trol box on the regulator.
9. Remove the old control box assembly from the
regulator.
10. Place the supplied universal bracket over the mounting
bosses of the regulator and secure with bolts retained
from in Step 7.
11. Place the CRA control box on the universal bracket and
secure it to the regulator with bolts, washers, lock-
washers and nuts provided.
12. Attach the nameplate to the front of the CRA control
box with retained hardware.
13. Ground the control box using the ground boss located
on the side.
14. Examine the control cable. Allow approximately 12" of
lead length to protrude past the end of the conduit nut.
This will facilitate connection to the top terminal strip
and knife switches located in the CRA control box.
15. Remove the cable grip nut and rubber cable grommet
from the cable entrance of the CRA control box.
16. Place the cable grip nut over the existing control cable.
Select, one of the two supplied cable grommets that
best fits the existing cable; place the grommet over the
control cable.
1 7. If the motor capacitor was located in the old control
box, do not cut the terminals from the capacitor wires.
Cut all other terminals from the end of the cable
conductors.
18. Strip the insulation back approximately 5/16 of an inch
on each lead to be connected in the new control box.
19. Insert the control cable into the control-box cable grip
connector, seat the rubber grommet, and tighten the
cable grip nut.
WARNING
Hazardous Voltage. The control box must be solidly
earth grounded. Failure to comply can result in severe
personal injury and equipment damage. VR-T216.0
DANGER
Explosion Hazard. Voltage regulators are subject to
high circulating current during bypass switching.
Refer to Service Information MN225003EN CL-7
Voltage Regulator Control Installation, Operation, and
Maintenance Instructions for information on the CRA
Control, and refer to the instruction manual supplied by
the voltage regulator manufacturer for specific safety
procedures for bypass switching. Failure to comply will
result in severe personal injury or death. VR-T214.0
DANGER
Flashover Hazard. Opening the CT circuit under load will
produce high voltages in the control box. Refer to the
instruction manual provided by the voltage regulator
manufacturer for specific safety procedures. Bypass the
regulator when installing the CRA to prevent opening
the CT circuit while the regulator is under load. Failure to
comply can result in severe personal injury or death. VR-T243.0
