CAUTION Use forced uninstallation only if normal uninstallation cannot be completed, the device is faulty or the oil pipes have already been disconnected.
CAUTION If forced uninstallation is not completed correctly, it may cause damage to the transformer.

Do not transport the DGA monitor without uninstalling it properly:

  • If the oil connections are not properly plugged, oil will drain out from the DGA monitor during transport.
  • Oil may contaminate the optical measurement module during transport unless you complete the uninstallation procedure successfully and lock the bleed valve manually.
You need to be on site to complete this task.
Wear protective eyewear and gloves.
  1. Connect to the DGA monitor user interface and log in as an Admin user.
  2. Stop the measurement mode by selecting Control > Stop Measuring.
  3. Wait for DGA monitor to enter Standby mode. Depending on the stage in the measurement cycle, stopping may take up to 60 min.
  4. Select Control > Uninstall.
  5. Select Forced uninstallation > OK.
  6. Select Confirm.
  7. Follow the instructions in the user interface.
  8. After completing the forced uninstallation sequence, follow the normal uninstallation instructions from step 19 until the end of the procedure to safely disconnect and transport the device.
