| Abstract: | This paper analyzes the operation characteristics of current protection on the fault components,the short existing time as well as directivity of load fluctuation and fault components.Then,it puts forward the combined use of fault components based on the different principles in order to avoid the influence of phase selection and non-fault-phase current on the operation correctness.Finally,it proposes a scheme that the directional elements on different principles and the various combination methods can be ad... |
