Abstract

PURPOSE: A power line path and circuit detecting method is provided to maintain voltage signal size under a maximum instantaneous value of a standard voltage in a connection point of a power line. CONSTITUTION: A power line is connected to a transformer. A power line detecting device executes a half-wave rectification process by connecting to a connecting point of a power line. The power line detecting device generates voltage signals by blocking current in a current applying state through protection resistance and the transformer.
