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.
CAUTION

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.
