<p>A detector for a malfunction of three-phase capacitor according to an embodiment of the present invention comprises: a passive element passing current through, the current being output from a neutral point connected with a three-phase capacitor; a detecting part detecting a direct current element by sensing voltage on both ends of the passive element; and a controller, which determines whether the three-phase capacity performs a malfunction by comparing the direct current element with a threshold value. The detector for a malfunction of a three-phase capacitor may rapidly and accurately detect whether the three-phase capacitor, which filters out a system control signal, performs a malfunction.</p> |
