Control of transformer losses in Canada

A new standard issued by the Canadian Standards Association, CSA C802, imposes maximum losses on power transformers 10 MVA and below. Included are distribution transformers, small power transformers, and dry types. Implementation will start through the publishing in mid 1994 of the Gazette by Ontario's Ministry of Energy. The Gazette will call for conformance to C802 after a lead time of one year to eighteen months, depending on the type of transformer. Other provincial energy ministries have been awaiting this development and are expected to follow suit shortly thereafter. The federal department, Natural Resources Canada, is also attuned to these actions and is expected to issue supportive legislation which will control movement of transformers across provincial and national borders.<
