3 Terms and definitions, symbols
3.1 Terms and definitions
GB/T 2900.95-2015 and GB/T 1094.1 as defined by the following terms and definitions apply to this document. For ease of use
With the repetition below lists some of the terms and definitions in GB/T 2900.95-2015.
3.1.1 Rated power
The specified value of apparent power marked on the winding together with the rated voltage of the winding determines its rated current.
Note 1. Rewrite GB/T 2900.95-2015, the definition of 2.1.3.
Note 2. The two windings of a two-winding transformer have the same rated capacity, so by definition it is the rated capacity of the transformer.
3.1.2 Default capacity assumedratedpower
Power transformer capacity to determine the flow of the rated capacity of the default value.
Note. The first time you can set the nameplate capacity.
