2.6 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 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.
•Operating altitude: DGA monitor is intended for use in altitude range -1000 … 3000 m.
If you have any questions, contact Vaisala for more information.
Performing a site inspection in person is a good idea. Take photographs of the
intended installation location, oil connections, and electrical connections. Measure
the amount of cable and oil pipe needed.
Chapter 2 – Planning The Installation
11

2.8.1 Installation Location of DGA monitor
The DGA monitor can be attached to the transformer chassis or to its immediate vicinity. The
location must fulfill the following requirements:
• The location must be close to the oil connections to minimize the length of the oil lines.
The maximum length of the lines is 10 m (33 ft) each.
• The location must be safely accessible from the floor without the need to climb or reach.
• There must be enough room and suitable supporting structures to install the DGA monitor
in a vertical orientation. The DGA monitor must not be tilted more than 5 degrees.
• If the Ground Mounting Set is used, there must be a level concrete surface that is at least
100 mm thick.
If you have many suitable locations, prefer the following:
• Locations that are protected from rain and solar radiation.
• Locations where the vibration and heat from the transformer are not directly conducted
to the DGA monitor.
OPT100 Installation Guide M211857EN-F
12

2.8.2 Recommended Locations of Oil Connections
You must build two oil lines between the DGA monitor and the transformer: one for intake of
fresh oil, and a return line for the measured oil. Make sure you have appropriate adapters for
connecting the oil lines to the valves. The maximum allowed length of an oil line is 10 m (33 ft).
Location of oil connections on the transformer may aect measurement performance.

Figure 1 Possible Locations of Oil Connections
1Oil reservoir. Not recommended.
2Side of the oil tank, top level. Good for returning the measured oil.
3Side of the oil tank, high enough from the bottom to enable proper oil movement. Good
for oil intake. Moisture response time is moderate depending on the oil volume.
4Straight section in the radiator’s outlet pipe. Good location for intake and return if the pipe
has guaranteed oil flow.
Oil flow guarantees that the sampled oil is representative and carries the returned oil away
from the inlet. Compared to the radiator inlet pipe, oil in the outlet pipe is cooler,
preventing unnecessary heating of the DGA monitor.
5Drain valve of the oil tank. To achieve representative measurement results, use only on
transformers that have pump-assisted oil circulation. Confirm there is no oil sludge or free
water in the bottom of the tank.
Make sure the valve you are connecting to has no oil sludge or free
water present.
CAUTION!
Chapter 2 – Planning The Installation
13

DGA monitor needs to pump oil in both directions during initialization and
maintenance. To make sure this is possible, check that:
• Intake and return valves are both below oil level in the transformer. There
should be no risk of drawing gas into the oil lines even when the flow is
reversed.
• There are no flow direction control valves on the oil lines.
After the oil lines are connected, you will not be able to take oil samples from the
valves. Consider adding a new sampling valve to the inlet oil line if you need to
continue taking oil samples.
