OPT100 is a device for monitoring the internal condition of an electrical transformer using dissolved gas analysis (DGA), also known as fault gas analysis. OPT100 is intended to be installed next to the transformer, and connected to it by two oil lines. OPT100 draws oil from a transformer, measures the concentrations of hydrogen, moisture, and several hydrocarbons in the oil, and returns the oil back to the transformer.

Measurement results can be transferred via communication interfaces to the substation's SCADA (Supervisory Control And Data Acquisition) system. The data is also available for viewing by human operators through the browser-based user interface.
