    In the selection of dry type transformers, how do I go about determining the proper rating of the transformer circuits?

    Rating Of Transformer Circuits

    There are some subjects in the CE Code that often become a source of heated discussions by the users. Selection of dry type transformers and selection of a proper rating of the transformers circuits is one of these controversial subjects.

    So, let’s try to clarify this seemingly complex issue. First of all - we need to refresh the understanding of a circuit rating in accordance with Rule 8-104. This rule states that the rating of a circuit or a feeder is the ampere rating of the overcurrent device protecting the circuit or the ampacity of the circuit conductors, whichever is less. This rule also states that the calculated load in a circuit shall not exceed the ampere rating of the circuit (i.e. shall not exceed the rating of the circuit O/C device and the ampacity of the circuit conductors).

      An ambitious agreement with the Ontario Power Authority requires Hydro Ottawa to help its customers reduce electricity usage in the nation's capital by 394 million kilowatt hours (kWh) by the end of 2020. This reduction supports Ontario's Long Term Energy Plan to lessen the need for new electricity generation sources through conservation.

      Hydro Ottawa is taking on the challenge to decrease electricity usage equivalent to removing 47,000 homes from the grid over the next six years. The aggressive target is nearly double what was previously expected from the province during the last four years of conservation programming. Leveraging existing provincial saveONenergy programs, the utility will be looking for new and innovative grass-roots conservation programs and incentives to engag...

      Industry Minister James Moore announced the passage of the Combating Counterfeit Products Act (Bill C-8) into law.

      Counterfeit and pirated goods are a growing threat to the Canadian and global economy. They undermine innovation, diminish brand integrity and threaten economic growth as well as the health and safety of Canadians.
