| Abstract: | Combined with practical case,the applicability of the uDL2 potential method,ground potential method,insula tion joint tester method,PCM leakage rate method and current loop method were studied in the evaluation of the insulation per formance of insulated joint.The results show that the quantitative evaluation of the insulation performance of insulated joints can be realized by comprehensive application of the five methods.The current loop test method can directly detect the magnitude and direction of the current in the pipe on both sides of the insulation joint,and the test result is the most reliable. |
