Installation position
The installation location is very important for the correct function of the MSENSE
®
DGA 9. There are
three possible installation locations in the case of a typical transformer:
Pos. 1
Cooler return line:
Install the MSENSE
®
DGA 9 on a straight pipe section at the connection between the un-
derside of the cooler and the transformer tank. To avoid vacuum the device must always
be mounted on the discharge side (beyond the elbow) of the circulation pump.
Remark: Only choose this location if constant oil flow through the cooling system is
guaranteed.
Pos. 2
Drain valve transformer tank:
The flange of the drain valve must be fitted at a minimum height of 40 cm for the
MSENSE
®
DGA 9 to be installed.
Pos. 3
Upper filling valve:
This position may only be used if the oil level is at least 100 cm higher than the centre of
the device flange. However, it is not recommended since it is difficult to operate or read the
device in this position.
Pos. 4
Never install the MSENSE
®
DGA 9 above the cooler or on the intake side of the
pump!
Remark: There must be good and constant oil circulation available at the installation location.
