  diana50Aug 23, 2025
  If you observe missing data or gaps in the graphs in the measurement view of your Vaisala DGA Monitor, this could be because measurement cycles haven't produced reliable results for some parameters. This can be caused by rapid temperature changes. Ensure the DGA monitor doors are closed and locked. Also, ensure that the DGA monitor is powered on and in measurement mode, not in standby or turned off.

  If the DGA monitor displays 'Oil inside cabinet', the float sensor inside the cabinet has been activated, indicating a possible oil leak. Check the device right away. Inspect inside the DGA monitor and oil lines to determine the cause and remove it if possible. This error may appear if the measurement has not been started with DGA monitor in an upright position. Install the DGA monitor in an upright position and perform the initialization to clear the error.

Why does my web browser warn me that the connection is not secure when connecting to the Vaisala Optimus OPT100 Monitor user interface?
- K
  Katherine Gallagher MDAug 28, 2025
  This warning appears because the user interface is secured using a self-signed certificate that your web browser does not trust, as the certificate is not publicly distributed. To resolve this permanently, create a trusted certificate and key, then configure the user interface security to use them. Alternatively, you can ignore the warning and proceed to the user interface; HTTPS traffic is always encrypted, even if the certificate is not trusted.

What to do if oil is leaking from the Vaisala Monitor?
- R
  Robert CastilloAug 27, 2025
  If oil is leaking from inside the DGA monitor or the connecting pipes, it may be due to a loose connection or faulty piping. Tighten any loose connections. If the leakage continues, stop the measurement and complete the uninstallation procedure before maintenance. If maintenance cannot start immediately, close the transformer valves to prevent more oil from leaking into the system.
