When conducting transformer maintenance, early detection of faults and potential failures in transformers is critical.

Dissolved gas analysis (DGA) was born of common dielectric coolant sampling procedures regularly performed by technicians. Fluid samples can reveal the relative value of key performance properties ...

DGA: This is a method to measure the gas concentrations in transformer oil. When the transformer has faults different types of decomposition gases are formed, such as hydrogen (H2), ethylene (C2H4), ...

Why install online DGA monitors? First and foremost, we need to understand why dissolved gas analysis (DGA) is important and why we should install DGA monitors on our transformers. Transformers are a ...

The application of artificial intelligence algorithms for transformer incipient fault classification using dissolved gas analysis (DGA) is an interesting engineering approach. However, there are ...

Manufactured by Pennsylvania Transformer in 1958, the aging transformer operated without significant issues for its first 50 years until 2010, when the first questionable gassing patterns appeared in ...
