Geomagnetic Disturbances: A Danger to the Power Grid

In 1989, the Québec grid collapsed as equipment protection relays tripped in a cascading sequence of events. Six million consumers were left without power for up to nine hours. The cause of this major outage was a geomagnetic disturbance (GMD). Geomagnetic disturbances occur during solar...

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...
