A modularized capacitor array includes a plurality of capacitor modules. Each capacitor module includes a capacitor and a switching device that is configured to electrically disconnect the capacitor. The switching device includes a sensing unit configured to detect the level of leakage of the capacitor so that the switching device disconnects the capacitor electrically if the leakage current exceeds a predetermined level. Each capacitor module can include a single capacitor plate, two capacitor plates, or more than two capacitor plates. The leakage sensors and switching devices are employed to electrically disconnect any capacitor module of the capacitor array that becomes leaky, thereby protecting the capacitor array from excessive electrical leakage.
