Summary

The construction of underground residential distribution systems has increased significantly since its start in the 1960s. Today, many areas require URD systems for new housing developments. As the number of URD systems in use continues to grow, it becomes more and more important for linemen to be able to locate and identify faults quickly so that power can be restored to customers. This 29-minute video describes methods that can be used to troubleshoot two types of problems that may affect URD systems: transformer faults and cable faults.
