Distribution underground cable evaluation

The evaluation of the total life cycle costs of underground power cable alternatives is an important analysis performed by distribution engineers. While it is a straightforward application of engineering economics, it must avoid significant distortions and deal effectively with uncertainty. The unique procedure described herein uses a simple, yet rigorous, approach for addressing future replacement costs and avoiding length of study period distortion when different lives are being considered. In addition, a concise and informative way of dealing with the major uncertainty-that of projected cable life-is included
