摘要： PROBLEM TO BE SOLVED: To shut down a cable run for fire prevention by monitoring voltage between lines of receptacles for the detection of a short circuit resulting in arc discharge, and discriminating a voltage waveform in normal operation from the one at the time of an arc short circuit. SOLUTION: An arc detector 1 is disposed on a receptacle, and a breaker 4, a voltage detecting line, and a power circuit 5 are connected. The power circuit 5 has a sufficient capacity to output stable voltage to the arc detector 1 even if an arc short circuit occurs. Test buttons 2-5 are switches for verifying the operation of the arc detector 1 for dividing power supply voltage by means of a test voltage divider, and applying the voltage lower than the power voltage to a filter 2-1. The filter 2-1 removes high frequency noise from the power voltage. The noises are superimposed on a house-wiring, and removed by filters to increase the circuit protection and detection precision of the arc detector 1. It is thus possible to detect and protect the arc short circuit, and the serial arc of the house-wiring on the downstream side of the receptacle.

摘要： PROBLEM TO BE SOLVED: To calculate the maximum voltage rise and eliminate setting by estimating a voltage for the neutral line of each power lines at the wire drop pole at a desired time. SOLUTION: V1a, I1a, V1b, I1b at the time (a) and time (b) are detected (step 1). The conditions of time (a) and time (b) are that I1a and I1b are different, and the actual drop pole voltage Vura at the time (a) between one power line and neutral line is equal to the actual drop pole voltage Vurb at the time (b) between one power line and neutral line. Here, the former half is that I1a and I1b are different due to ON/OFF of the load connected to one power line or change of output of single-phase 2-wire inverter 2. The latter half is that capacity of the commercial power system 3 is sufficiently larger than the capacity of the single phase 2-wire system inverter 2, and Vura and Vurb are equal under the condition that the influence on Vura and Vurb by difference of I1a and I1b is regligible because a load of the neighboring customers is connected between the one power line and neutral line.
