| Abstract |
Generally, a serial AC arc in multi-load configuration is difficult to detect because the line current contains multiple harmonic components corresponding to its compositive load characteristics. In this paper, serial AC arc algorithm using difference for fast fourier transform (FFT) variations of main line current was suggested and its effectiveness by applying into multi-load configuration was analyzed. Based on serial AC arc tests for multi-load configurations with different loads, the difference for FFT variations of main line current in each multi-load configuration was analyzed. The suggested algorithm was confirmed to detect the serial AC arc and was satisfied to be operated within the regulatory arc circuit breaker’s operation time for all multi-load configurations. |
