ABSTRACT:
A current and voltage detector for a distribution system is provided with a lower section, an upper section and a fastener for combining the lower and upper sections into one body. The lower section comprises: a first groove for receiving an electric wire of the distribution system; an optical type current sensor; an optical type voltage sensor; and a potential divider for supplying a voltage to the voltage sensor. The upper section comprises: a second groove for receiving the electric wire; and a U-shaped magnetic core for applying a magnetic field to the current sensor.
