Abstract (en)
[origin: EP0347304A1] The invention relates to an electric measuring transformer. More precisely, the present invention applies to monophased or multiphased transformers suitable to adapt an actual electrical value to a value compatible with a module for measuring, counting, control or monitoring. <??>The transformer (1) has at least one winding (5), a primary circuit (2), a secondary circuit (3) defining a transformation ratio (i1/i2) and in consequence its range of application. <??>According to the invention, it comprises means (6) to adapt the configuration of the transformer (1) as a function of the chosen range of application, and/or as a function of the application of the measurement, which carry out at least the switching of the winding or windings (5) in accordance with the chosen range. <IMAGE>
