Storing and transporting DGA monitor
Keep the DGA monitor and any installation accessories in their original packaging during
storage and transport. Keep the items dry and in conditions allowed by the storage
specification. Follow any handling instructions marked on the outside of the packaging.
After installation, store the packaging in a dry place. You can reuse it for storage and transport
later.
2.7
Reinstalling DGA monitor
If you want to relocate an already installed DGA monitor, you must prepare it for transport and
reinstallation by following the uninstallation procedure.
See OPT100 User Guide (M211858EN) for details.
2.8
Installation site requirements
DGA monitor can be installed and successfully operated in a wide variety of environments.
Note the following special considerations:
• Cold environments: Trace heating elements and thermal insulation may need to be placed
over the exposed sections of the oil pipes. Required heating power and insulation
thickness depends on the pour point of the transformer oil that is used. Temperature of
the oil in the lines must exceed the pour point with a reasonable margin in order to keep
the oil flowing normally during operation.
• Hot environments: Weather shield installation option will reduce the solar radiation load
on the DGA monitor. Consider placing the DGA monitor in a location that is not exposed
to direct sunlight.
