| description | The utility model relates to the field of discharge test on electrical equipment, and particularly to a partial discharge testing apparatus capable of simultaneously testing multiple transformers. The apparatus includes a frequency conversion power supply, an excitation transformer, a capacitive voltage divider, a compensation reactor, a peak voltmeter and a partial discharge instrument, wherein the frequency conversion power supply is connected with a frequency conversion power supply control box through optical fibers; and the apparatus includes at least one tested transformer, an inductor and a detection impedance box are in series with a low voltage input terminal of each of the tested transformers, the detection impedance box inputs a low voltage signal to the partial discharge instrument and used for detecting the quantity of partial discharge of each of the tested transformers, a high voltage output terminal of each of the tested transformers inputs a high voltage signal to the partial discharge instru |
