Safety of grounding systems

10th International Telecommunications Energy Conference, 2003
Problems connected with the grounding of central offices are discussed, and solutions are offered. Several examples are considered, including the case when a high-resistance connection exists between the grounding conductor and the distribution frame because of improper termination or faulty crimping. >
