Diagnostic Software for Testing High-Voltage Apparatus

Transformer Oil Analyst (TOA4) is a cutting-edge diagnostic tool for insulating fluid test data, including dissolved gas analysis (DGA), for high-voltage equipment.

Reliable and safe operation of the electric power grid requires confidence in the state of vital assets. This is constantly challenged by the ageing equipment, experienced staff retirement and budget constraints.

Addressing these challenges is required for the best possible maintenance of and capital planning for equipment like power transformers.

With a scientifically sound foundation developed during 25 years of research, TOA4 provides the most correct interpretation of DGA data available today.

DGA uses real-world reliability data to create an innovative statistical model that corrects fault gas production and transformer failures.
