Install A Bushing Adaptor - GE Kelman DGA 900 Plus Installation & Commissioning Manual

9.4.2 Install a Bushing Adaptor

The Bushing Adaptors are shipped with a plastic-threaded cap as shown in Figure 9-7.
Figure 9-7: Bushing Adaptor with cap
When removing the original test tap caps from the bushings, first check that they fit the
plastic-threaded cap from the new bushing adapter. If it is a good fit, continue with the
Bushing Adaptor installation. If the original test tap cap does not fit the plastic-threaded
cap, halt the installation and contact GE Technical Support.
Note: See Section 9.8 for the test procedure on how to verify the circuit integrity of
the Bushing Adaptor.
To install a Bushing Adaptor:
9.4.2.1 Check Bushing ID reference against Bushing Adaptor ID reference.
9.4.2.2 Remove the bushing test tap covers. The customer must retain the tap covers if
in the future the bushings are to be decommissioned.
9.4.2.3 Place the O-ring in its seat as shown in Figure 9-6 to form a seal between the
bushing adaptor and the tapping point surface.
Note: There are two spare O-rings supplied in the shipping package of each Bushing
Adaptor. Store these safely for future use should the Bushing Adaptor need to
be re-installed.
9.4.2.4 Apply the conductive grease to the bushing adaptor threads. The high
temperature anti-seize carbon conductive grease (supplied with the
installation kit) must reach all threads. To start, apply an even amount of grease
to the first few threads as shown in Figure 9-8.
