As far as the current reactor test is concerned, most of the reactors are single-measured and recorded for a certain parameter. For example, only the insulation resistance test, DC resistance test, high and low voltage power frequency withstand voltage or induction can only be performed on the reactor. One of the tests of withstand voltage and other tests requires frequent replacement of test instruments and test circuits during the test, and it is impossible to test multiple performance parameters at the same time. At the same time, when the existing reactor testing system performs high-voltage and low-voltage tests on the reactor, it needs to perform tests under high voltage or low voltage separately, and cannot perform tests under high voltage at the same time.

Although this patent can directly measure parameters such as single-phase or three-phase voltage effective value, current effective value, three-phase reactance, three-phase inductance, total active power and frequency, the performance test of low power factor test occasions can be carried out. However, it cannot meet the requirements of insulation resistance test, DC resistance test, high and low voltage power frequency withstand voltage or induction withstand voltage test for reactors under high and low voltage conditions at the same time.

Therefore, it is necessary to improve the design of the above-mentioned existing reactor test system, and provide a reactor test system that can simultaneously meet various performance tests of the reactor under high and low voltage conditions.
