Advancements in Dissolved Gas Analysis: Accounting for Gas Loss

Dissolved gas analysis (DGA) in transformers is a very successful periodic screening method to identify transformers that may be having problems. It is a symptom-based assessment of health, rather than a condition-based assessment. That is because the gases themselves do not cause failure, but are...

Advancements in Dissolved Gas Analysis: Risk Assessment

In general, the purpose of periodic screening with DGA for power transformers is risk assessment. Is any transformer likely to fail in service? If so, how severe is the problem? Previous articles in this series have described ways to improve DGA interpretation. In this article we provide a glimpse...

Substation Testing & Maintenance

Properly Grounded Substations

Adequate utility grounding improves power quality, but more importantly, it is essential for worker safety as well as public protection. Design is critical in maintaining a safe equipotential environment all around the substation. Construction is important to accommodate fault currents without...

Condition Monitoring in an Age of Modernization How (and why) to Adapt

The widespread application and use of electricity, which may now seem like a simple commodity, is considered one of the greatest technical developments of all time. However, keeping up with today’s demand for power is anything but simple: a vast amount of resources goes into maintaining a...

An Overview of Substation Maintenance: Its Evolution and Key Testing Practices

As electrical systems age, operating costs increase while reliability dwindles. Given most utilities and industrial facilities are highly capital intensive and have limited financial and other resources to make wholesale equipment replacements, regular maintenance is critical for controlling the...

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...
