采用杆状和环状两种简单天线，研究了利用火花/弧源辐射电磁能量作为检测燃弧故障手段的可行性。研究表明，用低调幅、兆赫频段的便携式天线可以替代传统的电弧检测方法和仪器，实现对低电压电弧/火花的检测。此外，电弧过程的前两个阶段，即初始辉光放电和瞬时电弧发展，都根据天线捕获的信号的起始时间和辐射光谱内容来区分。
A feasibility study of utilizing radiated electromagnetic energy from spark/arc source as a means of detecting arcing faults is conducted using two types of simple antenna, stick and loop. From the investigation, it is concluded that arc/spark of low voltage can be detected by portable antennas with frequency bands of low amplitude modulation and megahertz as an alternative method to the conventional arcing detection methods and their apparatus. In addition, each of the first two phases of arc process, initial glow-like discharge and transient arc development, is distinguished by the respective inception time and radiation spectral content of the captured signals by the antennas.
