| Abstract: | It introduces the theory of the rate of rise of current protection and current increment protection, uses 3UB61 protector on Guangzhou metro line 1 as an example, recounts the testing theory and method of these two protectors into particulars. It proves the testing method of these two protectors we applies from qualitative analysis to quantitative analysis has important practice meaning. |
