The invention relates to a capacitor measurement device and a reactor characteristic testing method, especially a characteristic testing method for a three-phase correlated capacitor device, reactor and compact-type capacitor device. The method comprises the steps: employing a three-phase symmetric frequency conversion power supply as a test power supply; changing the frequency through a frequency control measurement system, and obtaining the execution and response under different currents and voltages; building a series of equations to solve a problem that reactors are connected in series to form a three-phase integrated capacitor device, wherein the performance parameter measurement and testing method and calculation methods are used for an integrated capacitor device or the compact-type capacitor device with no other access points except the three-phase external connection points A1, B1, C1 and O1. The method can determine whether the reactor device or a reactor has a fault or not and whether the configura
