Frequently asked questions

What can I use the DGA Calculator for?

The main use is the calculation of fault types and checking if your transformer's DGA results exceed the typical values.

The fault type identification is based on Duval triangles and pentagons, while the typical values come from the standards IEEE C57.104-2019 or IEC 60599:2022. You can choose to use either method, adhering to either standard based on your personal preference and need.

In the Vaisala DGA calculator, these have been visualized to make calculations and viewing the results more intuitive.
