Detection and Analysis of Series Arc Discharge in Indoor Wiring Systems
نویسندگان
چکیده
In this paper, we simulated series arc on electric heaters, vacuum cleaners and incandescent lamps controlled by a dimmer to analyze the characteristics of series arc that causes electric fires. A high pass filter (HPF) was designed to detect arc signal only. The HPF consists of 2-stage coupling capacitors and detection impedance, and its low cut-off frequency of -3 dB was estimated to 3 kHz. By using the HPF, we could detect high frequency components included in AC voltage and discriminate series arc signals on most types of loads used in low-voltage indoor wiring systems. Key-Words: Series arc, Electric fires, Electric heater, Vacuum cleaner, Incandescent lamp, Dimmer, High pass filter, Low cut-off frequency

Arc Fault Circuit Breaker (AFCB) technology promises to minimize the destruction of wiring elements in aircraft caused by potentially dangerous arcing events. While AFCB technology can enhance aircraft wiring protection, it creates significant difficulties for the aircraft maintainer who must find the barely visible arc-traces and repair the causes of these arc fault events. Intermittent faults...

Nowadays, water supply is more limited and providing water is more difficult due to increasing population and demand for water. Thus, due to rainfall shortage and impacts of drought, the need for forecasting monthly and annual rainfall and flow discharge through time series analysis is acutely felt. One of the key assumption in time series is their static condition. However, hydrological time s...
