Renewable Insulation Liquids for Transformers

Turning electrical assets into green machines

BY RONNY FRITSCHE & GEORG PUKEL, Siemens AG

Transformers are one of the most important components of energy grid systems. They enable the efficient transport of electric energy from the location where the energy is generated to the location where the energy is needed. Transformers, especially power transformers, are conventional electric equipment based on physic concepts and materials developed decades ago, making it critical to implement new designs and...

Advancements in Dissolved Gas Analysis: NEI & Gassing Events

One of the most important steps when looking at DGA data is to decide whether the data support the existence of a fault that is actively breaking down the insulation before you try to use a triangle, pentagon, or gas ratio method to identify a fault type. Otherwise, you are diagnosing random...


The Role of AI and Machine Learning in Predicting Transformer Faults

AI and Machine Learning can predict transformer faults by analyzing dissolved gas data, thermal patterns, and vibration trends to identify insulation degradation, detect anomalies, and prevent costly power transformer failures before they occur. Why AI Integration into Transformer Diagnostics...
