Installation procedures
Figure 4. Figures A and B show proper installation of smart sensor on prepared conductor. Figure C shows incorrect
placement for installation.
Installation of smart sensor – underground
application
1.
Arm the sensor clamping mechanism by carefully
grasping both clamping arms, pulling them apart until the
trigger mechanism drops into place. Stops have been
built into the clamping arms such that they can only be
opened to the point where the trigger will latch (Figure 5).
2.
For applications where the cable diameter is less than
1 inch leave the clamp pads attached to the clamp arms.
On installations where the cable diameter exceeds
1 inch, remove the pads that are attached to each
clamping arm. Removing the pads will allow the clamping
mechanism to properly attach to larger diameter cables
(Figure 6).
3.
Attach the sensor to a hotstick using the pulling eye.
4.
Push the sensor onto the cable below the elbow at a
location shown in Figure 4 while holding the hotstick
horizontal. The triggering mechanism will release the
clamping arms and securely attach the device to the
cable.
Note:
Only the closed core current transformer (CT) need be
applied over the region of the cable where the
concentric neutral has been removed or double-backed
(Figure 5).
For installation on tape shield cable, the closed-core CT of
the sensor should be placed above the location on the
cable where the tape shield has been removed or trained
back as part of the cable termination. Location of the
sensor must be similar to Figure 2 on page 6 (C or D), or
Figure 4 (A or B), for proper operation of the sensor as an
FCI.
5.
Remove the hotstick.
Note:
On 200 A load-break elbows, the preferred installation
is demonstrated in Figure 4 (A), where the closed core
CT is located directly below the test point.

arm on a mechanism where cable diameter exceeds 1”.
