1. The invention concerns a system for testing alternating current transformer, comprising three current transformers, three balance indicators, a Wagner branch and a admittance current divider with an inductive divider, characterised in that the terminals marked (ZP1, ZP2, ZP3) of primary windings (UP1, UP2, UP3) of transformers (P1, P2, P3) are interconnected in point (P) and the terminal marked (ZW1) of the secondary winding (UW1) of the transformer (P1) is connected in point (W2) via the resistor (R3) to the unmarked terminal of secondary winding (UW2) of the transformer (P2), marked terminals (ZW2 and ZW3) of secondary windings (UW2, UW3) of transformers (P2 and P3) are interconnected in point (W1), whereas unmarked terminals of secondary windings (UW1 and UW3) of transformers (P1 and P3) are connected via resistors (R2 and R1) to the circuit ground (M1), and between the common connection point (W2) and circuit earth (M1), the balance indicator (WZ3) is connected, also between the common point (W1) and the circuit ground, components of the admittance current divider (ADP), capacitor (C), and resistor of (G) conductance are connected, whereas they are also connected to an inductive divider (DI), whereas the central terminal of the inductive divider is connected with the circuit ground (M1).<IMAGE>
