How to choose a suitable microcomputer relay protection tester

Choosing a suitable microcomputer relay protection tester requires consideration of the following aspects:

Firstly, it is necessary to clarify the test object and scope. According to actual needs, determine the type and scale of relay protection devices to be tested, such as overvoltage protection, undervoltage protection, overcurrent protection, short circuit protection, etc. Meanwhile, based on the rated current, voltage, and frequency of the tested equipment, select the corresponding measurement range of the tester to ensure that it can cover the actual parameter range required for testing.

Secondly, it is necessary to consider the accuracy requirements of the testing. Generally speaking, the typical accuracy of microcomputer relay protection testers is 0.1%~0.2%, but specific requirements may vary depending on the testing scenario. Therefore, when selecting a tester, the appropriate accuracy should be selected based on actual needs.

In addition, specific parameters for testing should also be considered, such as voltage, current, accuracy, frequency, etc. Select the corresponding relay protection tester according to these parameters to meet specific testing requirements.

In addition, understanding the functional characteristics of different models of microcomputer relay protection testers is also the key to selection. For example, single-phase microcomputer relay protection testers are mainly used to test equipment such as transformers and circuit breakers in power systems; The six phase microcomputer relay protection tester is suitable for scenarios that require stronger measurement capabilities and protection functions; The three-phase microcomputer relay protection tester is suitable for large-scale power system testing on site.

Finally, it is also very important to choose a microcomputer relay protection tester with reliable brands and services. Considering factors such as the manufacturer’s upgradability, warranty service, and price, choose a satisfactory relay protection tester.

In summary, selecting a suitable microcomputer relay protection tester requires comprehensive consideration of factors such as the test object, test scope, accuracy requirements, specific parameters, functional characteristics, brand and service. By comprehensively evaluating these factors, a microcomputer relay protection tester that meets the requirements can be selected to ensure the accuracy and reliability of the test.

ZCAR-802S is an industrial control three-phase relay protection tester, suitable for protection debugging of 10KV/35KV and below. The instrument has standard four phase voltage and three-phase current output, which can be used to test various traditional relays and protection devices, as well as modern microcomputer protection. Especially for transformer differential protection and backup automatic switching devices, the test is more convenient and perfect.
