IEC61869 CT PT Analyzer for Analysis the Excitation Characteristic of Current Transformer and Potential Transformer
Product Description
IEC61869 CT PT Analyzer for Analysis the Excitation Characteristic of Current Transformer and Potential Transformer
Why do CT PT Test?
The current and voltage transformers are a very important part of the power system. It can convert current and voltage values into suitable signals for various protection, control and measurement systems in the power system. The current and voltage transformer testing is a method of testing the performance and accuracy of the intestinal sensor and the inspection of its internal electrical insulation performance.
The main purpose of current and voltage transformers is to ensure the accuracy and reliability of the output signal of the current and voltage transformers, and to ensure that each department in the power system can correctly operate and ensure the quality and safety of the power system.
Technical characteristics：
High testing accuracy, typical value can reach 0.02%.
The instrument adopts advanced DC method principle and has fast excitation characteristic testing speed.
The GDVA-405 CT PT analyzer has a nameplate guessing function. For CT and PT with missing nameplates, the instrument will automatically provide the turns ratio, class, ALF, and rated burden.
Built in industrial computer, which is equipped with an embedded XPE system and provides self recovery protection for the system's C drive, effectively avoiding software system failures and virus attacks.
Easy to operate, all test items are automatically completed at once, reducing testing time for users.
Only a small voltage and power output are required, with a small size and light weight (net weight about 13KG). Easy to carry and transport, very conducive to on-site testing.
12.1-inch large color screen display, full English color graphic interface, convenient for human-machine exchange.
With strong data management capabilities, the test results can be directly generated into Excel reports on the machine and can be viewed and printed directly. The instrument can store more than 5000 test reports internally. The test results can be exported from a USB drive, which is very convenient.
