摘要： PURPOSE: A device for detecting the current of a neutral line and electricity distributing box with an active zero-phase harmonic filter are provided to install an active zero-phase harmonic filter in an electricity distributing box of a three-phase and four-wire power system, thereby attenuating zero-phase harmonic waves. CONSTITUTION: A neutral line current detecting device(100) detects the currents flowing in a neutral line of an electricity distributing box. An active zero-phase harmonic filter(200) reduces the amount of zero-phase harmonic currents which are inputted from the neutral line of the electricity distributing box. The detection unit detects information about the temperature of the active zero-phase harmonic filter. A controller(240) generates a PWM signal by analyzing the information. The active zero-phase harmonic filter is protected from an overload.

摘要： PURPOSE: An arc sensor and an arc protection device thereof are provided to optimally protect power facility from an arc accident by interconnecting the facility with a protection relay in a high voltage substation. CONSTITUTION: An optical fiber cable(13,14) transmits an optical signal for the detection of an arc and an optical signal which is converted by the arc. A lens(11) reflects the optical signal for the detection of an arc, which is transmitted through the optical fiber cable. The lens comprises a reflector element which reflects the optical signal for the detection of an arc. An optical detector(20) transmits the optical signal for the detection of an arc to the optical fiber cable.
