Operation
Isolating and grounding a cable requiring repair
Step 1
De-energize cables

Open switches at both ends of cable to be isolated.
(Refer to Figure 4.)

Determine that there is adequate working room around
the terminators for parking the insulated standoff
bushings and training cables.

Determine that there is adequate working room for
handling hotstick around apparatus cabinet.

Place insulating rubber blanket on the ground directly in
front of terminators.

Inspect and test all operating equipment for serviceability.

Connect grounding elbow of appropriate voltage class, to
system ground.

Connect ground leads of protective caps to system ground.

Step 2
Determine that cables are de-energized

Remove 200 A protective cap or arrester from T-OPII
terminators using hotstick and set aside in a clean,
protected area.

Insert test probe of phasing stick on volt meter into 200
A interface. (Refer to Figure 5.)

Determine that all cables are de-energized.

WARNING
Do not proceed until cables are de-energized.
Step 3
Provide a visible break

Clean and lubricate T-OP II insulated standoff bushing.

Mount T-OP II insulated standoff bushing in the apparatus
parking pocket using a hotstick. Tighten eyebolt to
ensure secure mounting. Ensure that the copper stud is
properlyinstalled in the bushing before moving cable.
(Refer to Figure 6.)


Clean and lubricate, mating interface of the O&T/Torque
tool with an approved lubricant.

Grasp eye of the O&T/Torque tool with a hotstick, pull eye
fully into the stick.
