Abstract

The subject addressed is renewal planning of medium voltage (MV) distribution networks using asset health data as input to cost-benefit analyses of renewal alternatives. The paper presents results and experiences from the testing of a new method (REPLAN) for renewal planning. Two network companies have carried out extensive inspection and assessment of the technical condition of 11-22 kV overhead lines. The data acquisition includes taking pictures of components that are in poor technical condition. Cost-benefit analyses of relevant renewal alternatives are then performed based on the asset health of conductors, poles, cross arms, insulators, pole foundations and stay wires. Choosing the right alternative for renewal can result in great savings and a significant lifetime extension of overhead lines.
