  • Page 13: General Information

    General information The MSESNE DGA 9 device is a permanently installed multiple “gas-in-oil” analysis system. It enables the individual measurement of oil moisture (H O) and the key gases dissolved in the oil: hydrogen (H carbon monoxide (CO), carbon dioxide (CO ), methane (CH ), acetylene (C ), ethylene (C...

  • Page 14: Mountinginstructions

    Mountinginstructions 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.

  • Page 15: Safety Notes On Installation

    Safety notes on installation The following safety notes must be strictly followed during installation. Otherwise no warranty claims can be made. Never remove the protective cap of the connecting thread before you are ready to install the device at the transformer valve. This cap protects the connection unit from damage by dust and other foreign matter.
  • Page 16 ® Never operate the MSENSE DGA 9 on a close transformer valve for longer periods. Please remove the device if this can not be prevented. Always heed the removal instructions. ® Never install the MSENSE DGA 9 on a knee pipe or pipe bend on the in- take side of the cooling system pump!! Turbulence in pipe bends can result in a vacuum that can cause problems on the device.
  • Page 17 Safety gloves must be worn during mounting of the device. If the unit is to be installed over 1 m, the use of personal protective equipment to prevent falling and specially trained personnel are neces- sary. The high weight means two people are required for mounting the unit. Use lifting equipment.

  • Page 18: Preparing Installation

    Preparing installation A visual inspection must be carried out on the device before installation. For this purpose, unscrew the two knurled screws and then remove the device protective cover.

  • Page 21: Installation

    Installation Once installation preparations have been completed, the MSENSE® DGA 9 can be installed. Installa- tion is divided into 3 steps: • Mechanical installation [4.4.1] • Electrical connection [4.4.2] • Initial start-up (4.4.3) 4.4.1 Mechanical installation The sequence for mechanical installation depends on the connection on the transformer side. There are 2 basic types of mechanical installation: •...

  • Page 25 • ® Now align the MSENSE DGA 9 by turning it clockwise until the vent screw is at the 12 o'clock position at the top. Make sure the device is fitted firmly in this final position. Remark: The device may only be aligned by turning clockwise. As soon as the device is turned anti-clockwise for alignment, mounting must be carried out again! Note!!! When thread sealing tape is used, screwing the device beyond the 12...
  • Page 26 Note!!! The following steps must be carried out in accordance with company procedures. Work carefully and prevent air getting into the transformer. Use a bucket to collect any leaking oil. • Unscrew the vent screw by 3 or 4 turns anti-clockwise using the long size 4 hexagon key (vent- ing is active).
