readings; however, the lower operating temperatures and ease of access
make this location a valid alternative choice.
Figure 2: Mounting Locations of the H201Ti on a Transformer
Also, note the following points:
1.
The H201T
i
must always be easily accessible. The distance between the valve
and the ground must exceed 30cm (12in) to install and wire the H201T
i
.
2.
Do not install the H201T
i
on an elbow (see Figure 10) or a fitting box. The
turbulent oil flow at these locations may result in inaccurate gas level
readings.
3.
If the H201T
i
is mounted directly on the wall of the transformer tank, ensure it
is installed below the oil level.
4.
No obstructions (baffle, pipe, etc.) must exist behind the valve (inside the tank).
5.
Regardless of the selected location, it is recommended to mount the H201T
i
horizontally. If no horizontal valve is available, a vertical installation may be
acceptable; contact General Electric Customer Service (contact information
can be found at the bottom of page 2). If the H201T
i
is installed vertically,
note the following points:
-
The sensor’s threaded extremity must be oriented upward.
