The relay protection tester is also called a three-phase relay protection tester. The internal structure part is an electronic circuit design, which is susceptible to strong electromagnetic fields and strong magnetic fields. The grounding shield of the shell is more conducive to improving the office environment of the relay protection tester. The protection should improve the safety and reliability of the relay protection tester. In order to better ensure the safety and reliability of the microcomputer relay protection tester, it is necessary to suppress the interference source, block the coupling channel, improve the anti-interference of the sensitive power circuit, use automatic identification technology and fault-tolerant design to ensure the microcomputer relay Protect the safety and reliability of the tester. To ensure that the relay protection tester equipment stops running.

       The daily maintenance of the relay protection tester should be strictly implemented, develop good habits, pay attention to the cleaning after use, and a series of operations such as maintenance and power failure:

 

       1. Perform regular inspections and inspections of the relay protection tester when on duty, and keep a record of the date of use;

 

       2. Do the finishing work of using the miniature relay protection tester. The finishing work needs two people to prevent accidentally touching the instrument, keep a safe distance from other live equipment, and avoid personal electric shock;

 

       3. Perform infrared temperature measurement on the relay protection tester regularly to detect poor contact and heat as soon as possible;

 

       4. Regularly check and print the printer of the relay protection tester, and the data will be lost;

 

       5. Check the accuracy error, and whether the failure analysis is performed in time after the failure occurs;
