The replacement procedure may be performed in the shop or the field.
1.
Disconnect the GE "position indicator plug assembly" from the bottom of the position indicator to short-circuit the internal CT.
IMPORTANT:
GE regulators incorporate a control-cable disconnect device. The device has an internal CT short-circuiting scheme that shorts the internal current transformer circuit when the control cable is disconnected. If there is doubt as to whether or not the CT shorting device is functional, it is recommended that the regulator be bypassed or removed from service to remove load current from the regulator which would render the CT circuit safe to open during installation of the CRA.
Refer to the appropriate GE regulator instruction manual for specific information.
2.
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 or mark for reference later.
