S注入法"与电压互感器
S’s Signal Injection Method and Voltage Transformer
【摘要】 介绍了"S注入法"选线定位新原理,分析了TY系列选线定位保护在实际应用中加零序PT、不加零序PT及三相三柱电压互感器的接线方式,并指出这些接线方式除适合"S注入法"外,还具有消谐功能。
【Abstract】 Introduces a new principle of a S’s signal injection for identifying fault line and locating fault point. Analyzes the installed null PT, no installed null PT and three phase and three pole connection manners of voltage transformers in the practice application of the identifying line and locating position protection of TY series. And points out these connection manners adapt to the S’s signal injection, and besides, have the function of eliminating harmonic waves.
