Abstract

Direct current (DC) facilities are increasing with the spread of renewable energy such as photovoltaic power generation. DC series arc may occur in poor contact or disconnecting in the facilities and cause fire incidents. This paper presents DC series arc generation experiments in air considering actual failure conditions, and Wavelet transformation analysis of the measured current waveform. Using the obtained results, a method of detection of arc generation in low-voltage DC facilities is proposed.
