Defects of Microcomputer Relay Protection Tester
Malfunctions include the operation of output relays and watchdog contacts, the reset of microprocessors, alarm or trip indication, acceptance of corrupted information over the communication link and the corruption of saved information or settings. The abnormal phenomenon of the microcomputer relay protection tester is often at the system level, but the cause of the fault is at the component level and material level, and the multiple possibilities of the fault cause make it difficult to locate the fault. However, during use, the relay protection tester may encounter various faults. The following is an analysis of common faults and their causes: 1. In this paper, the characteristics of the equipment itself and the external environment are comprehensively considered, and. Selection of Test InstrumentsThe main test instruments for microcomputer protection devices are: microcomputer relay protection tester, three-phase current generator, and multimeter. In the author's opinion in order to verify the proper operation of complex multifunctional microprocessor-based protection devices.

What is static relay protection
In, a static relay is a type of, an electrically operated switch, that has no moving parts. Static relays are contrasted with, which use moving parts to create a switching action. Both types of relay control electrical circuits through a switch that is open or closed depending upon an electrical input. Static relays have been designed to perform similar functions with the use of electronic circuit control a.
