The microcomputer relay protection tester is a computer-controlled testing instrument for power system protection devices. It has the characteristics of high precision, multifunctionality, and easy operation, and can be used for testing, calibrating, and diagnosing relay protection devices in power systems. The following will introduce the selection principles of testers to help users choose testers that are suitable for their own needs.
Selection principles
1. Test object:
Determine the type and scale of relay protection devices to be tested according to actual needs. Common test objects include overvoltage protection, undervoltage protection, overcurrent protection, short circuit protection, etc.
2. Test scope:
Select the corresponding measurement range of the tester based on the rated current, voltage, and frequency of the tested equipment. Ensure that the tester can cover the parameter range required for actual testing.
3. Accuracy requirements:
Select the appropriate testing instrument for accuracy based on the accuracy requirements of the test. Generally speaking, the typical accuracy of microcomputer relay protection testers is 0.1% to 0.2%.
4. Functional requirements:
Select the functions of the tester according to actual needs. For example, some testers can perform comprehensive tests such as phase, frequency, and time, and can also simulate different fault situations for testing.
5. Convenience of operation:
Choose a tester with a user-friendly interface and simple function settings. Considering the user's usage habits and abilities, ensure that the tester is easy to operate, learn, and use.
6. Data recording and analysis:
Whether the tester has data recording and analysis functions, as well as data transmission methods (USB, network, etc.), is of great significance for the storage and subsequent analysis of test results.
7. Reliability and Security:
Choose a testing instrument with high reliability and protective measures. Including overload protection, overvoltage protection, short circuit protection, etc., to ensure the safety of operation and testing processes.
