FIELD: measurement equipment.
SUBSTANCE: device for scale transformation of current comprises an additional load resistance in series with the third outlet winding of the second transformer and the outlet winding of the first transformer. At the same time it is possible that in the device for scale transformation of current the additional load resistance is made in the form of serially connected the additional load resistance galvanically isolated from the main load and the third transformer, so that its primary winding is connected in series with the outlet winding of the first transformer, and they have one common terminal, and the additional load resistance galvanically isolated from the main one is connected to the secondary winding.
EFFECT: high accuracy, small weight and dimensions, expanded range of output capacity of the device corresponding to various types of loads and modes of operation, which makes it possible to widely apply such device in measurement systems and automation systems.
