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" , leave the clamp pads attached to the clamp arms.
On installations where the cable diameter exceeds 1" ,
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 3 while holding the hotstick
horizontal. The triggering mechanism will release the
clamping arms and securely attach the device to the cable.
N ote: 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 (C or D), or Figure
4 (A or B), for proper operation of the sensor as an FCI.
5. Remove the hotstick.
N ote: On 200 A loadbreak elbows, the preferred installation
is demonstrated in Figure 4 (A), where the closed
core CT is located directly below the test point.
