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 (3.9 in) thick.

  • Avoid locations where strong water jets, such as fire extinguishing systems, are directed at the unit and especially the seals and cable glands of the unit.

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.
