摘要： A composite electric circuit breaker, and method thereof, is configured to detect signals regarding arc faults, overcurrent, and earth leakage. Arcs and electric currents are detected by a current transformer and earth leakage is detected by a zero phase current transformer. A variation of electric current, the number of arcs which are generated per a unit time, a present electric current value, and electric current earth leakage are combined to judge whether arc faults occur to then interrupt an electric power supply. Temperature is measured on a printed circuit board, and if temperature rise occurs, the electric power supply is interrupted, and an interruption cause is displayed. Electric accidents and occurrence of fires are prevented simultaneously and more accurately. The interruption causes can be confirmed, analyzed and externally monitored through a network, to thus maximize efficiency of electric management.

摘要： Apparatus includes an arc wave generator for testing an arc fault circuit interrupter (AFCI) for use in a test system for testing whether or not an arc fault circuit interrupter (AFCI) is operating normally, in which a false arc is generated for use in testing the arc fault circuit interrupter (AFCI). The arc wave generator includes a rectifier which receives a commercial power source as an input source and rectifies alternating-current voltage of the commercial power source to generate a rectified signal. A drop resistor drops the voltage of the rectified signal to generate a voltage-dropped signal. A mono-stable multivibrator adjusts a voltage level and a pulse width of the voltage-dropped signal and generates a pulse signal which is used to generate a false arc for testing the arc fault circuit interrupter (AFCI). Thus, a false arc is generated with a simple circuit to accurately test the actions of the arc fault circuit interrupter (AFCI).

摘要： Infrared sensor that can make a temperature compensation by itself, and method for compensating a temperature thereof, are disclosed. The infrared sensor preferably includes a substrate, a diaphragm formed on the substrate, and a first thermopile sensor formed on a region of the diaphragm for sensing an infrared radiation emitted from a measured object and infrared radiations emitted from regions other than the measured object. A second thermopile sensor is formed on a region of the diaphragm and connected to the first thermopile sensor for sensing the infrared radiations emitted from the regions other than the measured object. A housing protects a front face of the substrate including the first, and second thermopile sensors includes an infrared filter in the housing over the first and second thermopile sensors for transmission of infrared radiations, and a reflector reflects the infrared radiation emitted from the measured object toward the first thermopile sensor. The method for temperature compensation can include the steps of letting an infrared radiation from a measured object be directed to the first thermopile sensor and letting infrared radiations from regions other than the measured object be directed to the first and second thermopile sensors, respectively, sensing the infrared radiations in the first and second thermopile sensors directed thereto, and making a temperature compensation for the infrared radiations from regions other than the measured object using the first and second thermopile sensors to provide a temperature component of the measured object only.
