Analysis of Residual Current Operated Circuit Breaker Test Circuit Design
Based on the test device clause in the Standard of GB/T 16917.1,this paper discusses the potential risks in the operation of button testing,which during the use of RCD at the application side.It analyzes the design of ampere turns and resistance selection in conventional test circuits,and proposes design schemes for double break point structure,trigger type test circuit,and self check type test circuit to improve electrical safety.
