GDBC-901B Touch Screen Transformer Turns Ratio TTR Tester with Neutral Point test
(With Lithium Battery)
Test items that can be completed by GDBC-901B Touch Screen Transformer Turns Ratio TTR Tester:
1) Voltage ratio measurement of three-phase or single-phase power transformer.
2) Voltage ratio measurement of three-phase or single-phase voltage transformer.
3) Turns ratio measurement of three-phase or single-phase power transformer and voltage transformer.
4) Vector group test of three-phase power transformer.
5) Tap position detection of three phase power transformer.
6) Phase angle difference measurement of power transformer and voltage transformer.
Other Functions:
Micro printer integrated for test results print.
USB interface for test results data upload
Making word report for uploaded test results with PC software.
Compared with other Transformer Turns Ratio Testers, New design GDBC-901B Transformer Turns Ratio Tester has the following characteristics:
1. More suitable for IEEE standards: There are neutral point O connection for both primary side and secondary side connection. So that the tester can measure both turns ratio of primary winding to secondary winding with IEEE standard . Also compliant with IEC standards.
2. All three phases are real test results: GDBC-901B generates the sine voltage signal required for testing through a three-phase electronic AC voltage source. The distortion of the test voltage waveform is low, and the test voltage is stable, resulting in better test repeatability and higher accuracy.
3. Equipped with a neutral point test: There are neutral point O connection for both primary side and secondary side connection
4. Touch screen operation: All operations can be completed through the instrument's built-in touch screen.
5. Powered by lithium battery: 12V 15000mAH. Once charge can working more than 10 hours during on site test.
