The object of the invention is to increase the accuracy of voltage regulation, to make easier the operation of voltage regulator and to decrease the consumption of energy at the customer's side. The proposed transformer's voltage regulator (fig.2) comprises two-level measuring device (1), logical elements OR, AND, NO (3,5,4,2), time delay unit (6), data output elements (7,8), data input/output unit (11), data display unit (12) and setting unit (13). The regulator is characterised in that is additionally provided with special unit (14) for calculation and input of inner settings. One input port of this unit is connected with the start button (15) of the regulator. The other input port of unit (14) is connected with the output port of data input-output unit (11), but output is connected with the input port of the setting unit (13). The calculated inner settings corresponding to the manual voltage settings for minimum and maximum load modes are introduced through the setting unit (13). Analysis of transformer voltage and corrective action of settings are performed by regulator itself when disturbing influence from outside is received.
