Abstract:
    The invention discloses a method to divide the surge and the short circuit. It is based on the characteristic of the oscillating current envelope line in the electric power system. It finds the relation between the constant component Io and the alternate component Im in the condition of mishandling in the distance protection part because of the oscillating. When the Im
