Which devices need to be tested for power system access?

See if you are on-site online testing or laboratory testing? On-site inspection includes ML380 series centralized meter reading terminal on-line tester produced by Shanghai Zhongrong Instrument Electric Company, which mainly tests the functions of concentrator and collector, and can also test the accuracy of electric energy meter! If you are in the laboratory, you usually use a test equipment, which contains a program-controlled power supply. In addition to testing the function of centralized meter reading terminal, you can also test its communication technical indicators! There are many detection devices in this field, such as YC 1893F series automatic detection devices for low-voltage centralized meter reading terminals produced by Yangcheng Science and Technology Group Shanghai Branch.
