Detection of faulted phase type in distribution systems based on one end voltage measurement
A two steps technique for detection of faulted phase type is proposed. The algorithm consists of Clark transformation and phase angle shift calculations. We use the Clark transformation to identify the fault polarity relative to ground. We use the phase angle shift values to classify the phase faulted type. Technique is tested at different faulted type conditions with accurate results.
