Why event-based fault type identification is better than a sample-by-sample approach

Introduction Fault type identification is an important step in dissolved gas analysis (DGA). When a significant amount fault gas production is detected in a transformer, we want to know what kind of physical condition could be responsible for the gassing. Knowing the type of fault can help to...

Transformer Monitoring

Understanding Bushing Failure Modes and Monitoring for Optimal Transformer Health

Monitoring the health of bushings is vital for ensuring the reliability of transformers, especially in high-stakes environments like power grids and industrial facilities. Bushings, critical components of transformers, are prone to various failure modes that can lead to operational inefficiencies...

Transformers and the power grid: A look at the critical components of the electrical system

BY THE ELECTRO-FEDERATION TRANSFORMER COMMITTEE*

Electrical transformers are a vital ingredient to the power grid. Without these assets, electricity generation and transmission over long distances would not be possible nor would it power urban centres and industrial complexes. Once a thriving Canadian industry, transformer manufacturing has been challenged in recent years by increasing competition from offshore players with dumping margins...
