Abstract: The present invention relates to a monitoring method for identifying the abnormality and soundness of a large power facility (a power generator, a transformer, a power line or the like) in operation, which is installed in a power plant and a substation of an electric power company or a power receiving room of a factory or the like, and a hardware apparatus therefor. To achieve the purpose, the present invention employs a method of monitoring a facility by measuring an electric circuit integer in the facility, which inevitably changes when the facility is abnormal. In the method, a circuit integer is measured by establishing a primary algebraic equation (including unknown circuit integers) receiving voltages and currents of input and output terminals of a facility and indicating a voltage-current relation of each part in accordance with an equivalent circuit model suitable for the scale of the facility, and analyzing the same. Here, in the case of an equation with two unknown integers, two simultaneous equations are needed (when ″T″ and ″π″ are equivalent), and thus, the equation which has been measured and established on the first step, is stored via a predetermined procedure, and then, is retrieved afterward to be simultaneously used. Since each circuit integer obtained in such way indicates certain physical properties of the facility, when a change is observed, the abnormality of the facility can be predicted and monitored, and the facility can be monitored through its change trend, a graph and a diagram, a message and a warning means.
