The invention relates to the electric energy quality monitoring apparatus self-test technology field and the invention is an electric energy quality monitoring apparatus self-test apparatus and a self-test method thereof, wherein the electric energy quality monitoring apparatus self-test apparatus comprises a standard source, an electric energy quality monitoring apparatus, a switch and a test terminal; the standard source and the electric energy monitoring apparatus are connected through a test cable; the switch is connected with the test terminal, the standard source, and the electric energy monitoring apparatus through network cables; and the test terminal comprises an automatic test layer and an apparatus test side editing layer. According to the invention, the self-test apparatus can realize closed loop automatic test; after the test is finished, a test report with a standard format is automatically formed, so that the phenomena of lacking items and missing items due to human factors in the test are prevented; the potential safety risk due to incomplete test of the apparatus is lowered; the normal, standard and efficient automatic test is realized; and the purposes of lowering the requirements to worker, simplifying the working processes and normalizing the data format are realized.
