The microcomputer relay protection tester can perform the following test items:
1. Electrical characteristic testing of switches, such as closing time, opening time, closing current, opening current, etc.
2. Test the excitation characteristics of closing, such as closing time, closing current, closing stability, etc.
3. Testing of opening excitation characteristics, such as opening time, opening current, opening stability, etc.
4. Testing of overvoltage protection characteristics, such as the action time, action voltage, and action characteristics of overvoltage protection.
5. Testing of overcurrent protection characteristics, such as the action time, action current, and action characteristics of overcurrent protection.
6. Zero sequence protection characteristic testing, such as the protection action time of zero sequence current, protection action current, etc.
7. Instantaneous protection characteristic testing, such as the action time and current of instantaneous overcurrent protection.
8. Time protection characteristic testing, such as measuring the time current characteristic curve.
9. Test the characteristics of inverse time protection, such as the action time and current of inverse time protection.
10. Frequency protection characteristic testing, such as the action time and frequency of frequency protection.
11. Trip frequency testing, such as measuring the number of trips.
The above are only some test items that can be carried out by microcomputer relay protection testers, and the specific test items will be determined based on actual needs and the type and specifications of relay protection equipment.
The ZCAR-1600C microcomputer relay protection tester is an important testing tool for ensuring the safe and reliable operation of power systems. On the basis of referring to the "Technical Conditions for Microcomputer Relay Protection Test Devices" issued by the former Ministry of Electric Power, the instrument carefully summarizes the development and production experience of previous generations of products, and adopts modern digital technology, high-precision electronic devices, microcomputer systems, new circuits, and new structures to develop. It can independently complete device testing in professional fields such as microcomputer protection, relay protection, excitation, metering, and fault recording, and is widely used in scientific research, production, and electrical testing sites in industries such as power, petrochemical, metallurgical, railway, aviation, and military.
