Lab VIEW based implementation of remedial action for DC arcing faults in a spacecraft

In this paper remedial action for DC arcing faults in spacecraft has been designed and implemented using Lab VIEW. The Lab VIEW is an innovative graphical programming system designed to facilitate computer controlled data acquisition and analysis. DC arcing faults in spacecraft has been designed and implemented using the experimental data obtained at NASA Glenn research center. It is important to keep the continuity of the power supply and at the same time increase the reliability of spacecraft energy power system. In the frequency domain, fast Fourier transformation (FFT) is used for the feature extraction of the fault signal and odd harmonics frequency components of the phase currents are analyzed.
