The relationship of the potential defect and life with life characteristic and information were studied, and the life prediction depending on life initial information was introduced. The performance degradation rules of the relays were studied based on the sequence information matrix that contains many parameters and sampling points. The mass of data related had to be compressed. Some methods combined with neural network were used to select the sample of sequence information, and the choosing method of samples was determined by comparing the errors. To extract the key performance parameters, the column vectors of sequence information matrix were processed with principal component analysis. The proper value function was constructed to acquire the characteristic quantity which can describe the comprehensive performance reliability of the relays. The performance degradation model of the relays was studied.
