This study refers to the characterization techniques of power cables. The cable failure brings about an enormous loss of power supply and the immense expense for cable replacement. These characterization techniques can be used for identifying a cause of failure and for improving a quality of equipments. Also, these play an important role in the detection of premature failure. From the characterization results of failed cables, water trees grown from insulation shield had a relation with ionic impurities of insulation shield. The main causes of cable failure were void, non-crosslinking, convolution from manufacturing process. In order to maintain a cable reliability, quality control is needed strictly. It can be possible to estimate a residual lifetime of power cable using characterization techniques.
