Abstract

A real-time insulation detector for feeding a high-frequency low-voltage signal is electrically connected with a power system, and the power system includes a power circuit comprised of a main power circuit and plural branch circuits, a plurality of power transformers are arranged in the main power circuit and the plural branch circuits, and each current power transformer has a positive electrode point and a negative electrode point arranged on a low-voltage side thereof, the real-time insulation detector contains a central controller, a signal generator, a circuit selector, a plurality of detection circuits, plural first safety circuits, and plural second safety circuits. Thereby, the real-time insulation detector automatically feeds a high-frequency low-voltage detection signal, and when the power system runs in an uninterruptible power network, the central controller judges aging insulation comes from which one cable or component of the power system.
