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
