The invention discloses custom power equipment detection circuit and equipment. The custom power equipment detection circuit comprises a power circuit generating power, a voltage disturbance and generation circuit, a load circuit connected with the custom power equipment, a collecting device connected with the custom power equipment and a processor. The voltage disturbance and generation circuit is connected between the custom power equipment and the power circuit and used for sending disturbance voltage, generated according to the power, to the custom power equipment. The load circuit is used for providing load for the custom power equipment. The collecting device is used for collecting operation parameters of the custom power equipment. The processor connected with the collecting device is used for determining performance parameters of the custom power equipment according to the operation parameters. By the use of the custom power equipment detection circuit and equipment, solved is the problem of the prior art that whether or not the custom power equipment runs normally is undetected, thus the custom power equipment is unsafe and short in service life; and the custom power equipment is detected by simulating actual working conditions.
