Fusing in Modern HFC Network for Improved Network Availability

摘要

Fusing or protection against over-currents in the cable TV coaxial distribution network is an area in which many misconceptions found a way into coaxial plant powring design. The origins of these misconceptions are numerous, but most of them can be traced to the interpretation of the rules of fusing in the power plant and power installations. A direct implementation of these rules results in lower reliability of the netowrk without meeting the objectives of equipment and personnel protection, and fault isolation.
