FIELD: electrical equipment.
SUBSTANCE: invention relates to electrical engineering and is used for resonance tests, that is for the case when the inductive resistance of the tested transformer (reactor) 8 is equal to the resistance of battery 9. Summary: installation for testing transformers comprises converter 3 of three-phase mains voltage to alternating voltage, controlled by frequency in value, output transformer 3, diode bridge 6 with throttle 7. Diode bridge 7 is connected to bridge poles, and to phases of bridge are connected ends of primary or secondary winding of transformer 3. Capacitor 9 is connected to tested transformer 8.
EFFECT: technical result: increased reliability.
