OPT100 Installation Guide
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.
