isolation and auto transformer

Transformer has a big family. That is to say, there is a variety of types of it. For example, current Transformer, pole type transformer, isolation and auto transformer and so on.

The type we use of it depends on the use and role of it. And the size of transformer also has a wide range. Today let’s pay attention to the story of its size.

If you want to see the large transformers, you may go to a substation which contains a large capacity. Now let’s go to the Cathedral Square Substation in Vancouver.

To increase the reliability of existing electrical infrastructure and address growing demand for electricity in the downtown core, BC Transmission Corporation (BCTC) has installed a third electrical transformer at Cathedral Square Substation in Vancouver. BCTC worked closely with BC Hydro on this project.

The transformer was moved from the waterfront rail yard to Cathedral Square Substation in the early morning hours of Sunday, February 1 on a 150-ft-long trailer. A 500-ton crane was required to lift the transformer from the trailer and lower it into the substation.

Cathedral Square Substation Cathedral Square Substation is located underground on the corner of Dunsmuir and Richards Streets in downtown Vancouver. Constructed in the early 1980s, Cathedral Square Substation now serves approximately one-third of the downtown electrical load. Currently, two 25-year-old transformers that have a life expectancy of 50 years serve Cathedral Square.

Zero Phase Current Transformers

Pole Type Transformer

The data of this transformer:

Weighs 176 tons

Measures 30 ft long by 12 ft wide by 16 ft high

Installation required a 500-ton crane

Transported by CP Rail from St. Louis to Vancouver waterfront Transformer cost is approximately $3.4 million.

Wow it’s amazing!

If you are a careful person and knows a little about electrical engineering, you can found the transformer applied in many respects in our life. And there are many transformers with much smaller sizes used in motor vehicle, family circuit, electronics product. So They all have play a great role.
