摘要

With the limited coordination that can be achieved using conventional recloser fuse-saving, customers experi- ence frequent momentary outages for faults on other parts of the system as the breaker or recloser trips in a futile attempt to save fuses. When a fuse-blowing strategy is employed instead, any fault on a lateral - even a temporary fault due to conductor slapping or animal contact - will cause fuses to operate and results in frequent and lengthy customer outages. The new fuse-saving technique described in this paper bridges the gap between the two conventional fuse coordination philosophies. By using custom-generated fuse-saving curves and only tripping when the fuse may actually be saved, the best combination of reliability and overcurrent protection is achieved. Using a separate operating sequence for fuse-saving trips allows the full use of pulseclosing and fuse-saving together. Additionally, tripping only the faulted phase(s) for the fuse-saving trip greatly reduces MAIFIE and can likely be used even in locations where extended single-phasing conditions are not acceptable.
