DEVICE FOR DETECTING CORONA DISCHARGE IN AN ENCLOSED ELECTRIC DEVICE |
摘要 |
In an enclosed electric device in which a conductor to be charged with a voltage is supported by an insulation support in its enclosing metal case, an electrode is disposed on or in the insulation support so as to provide a first static capacitance with respect to the conductor and a second static capacitance with respect to the metal case. A corona discharge detector is connected between the electrode and the metal case and adapted to detect, with the first static capacitance used as a coupling capacitor, a corona discharge occurring from the conductor and the insulation support.
