AI Technical Summary

Technical Problem

During the detection process of the relay protection tester, the connection of the voltage or current output ports is manually switched, and the reports generated after detection are independent and need to be manually compared, which is prone to errors.

Method used

An automatic detection system of relay protection tester is designed, including an automatic detection device, a PC, a switch and an electronic load. By setting a voltage channel conversion module and a current channel conversion module in the electronic load, automated detection is realized, and a data storage/comparison module is set in the automatic detection device to generate multiple sets of data comparison reports.

Benefits of technology

The automatic detection of the relay protection tester is realized, which reduces the steps of manually switching connections, improves detection efficiency, and reduces errors through data comparison and improves the comparison accuracy.
