1. Input single power, internal digital combination standard sine wave test source output
2. Phase angle measurement function: measure the phase angle between high voltage side and low voltage side. Measure the transformation ratio and angle of "Non integral point" transformer.
3. It can conduct single-phase measurement and three-phase winding automatic test. Three phase turn ratio value, phase angle value, error, tapping position, tapping value can be measured for once.It also can identify connecting group number automatically.
4.Testing results can be displayed in the form of digit and hexagon vector diagram, which makes transformer connecting group can be made out obviously.
5. With blind test function: There is no need to choose connecting method and group. When measuring Y/Y transformer, no external short-circuit is needed, connecting method can be shifted automatically according to the chosen testing contents.
6. With tapping test function: TTR and TTR error in the position of each tapping switch can be gauged quickly. Just input rated TTR once, instead of inputing over and over again, TTR error in tapping position can be calculated.
7. With functions of turns ratio measurement and voltage TTR measurement.
8. With 5.6 inch LCD, the effect of data & figure display is visualized and fine.
9. With small size and light weight, it is easy to carry.
10. With built-in high capacity chargeable lithium battery. Test can be conducted without any power supply on site, and once the battery is charged fully, it can make measurement for more than 500 times continuously.
Product Introduction
Transformer Turns Ratio Meter is a high-precision, portable ttr meter equipment engineered for comprehensive transformer testing, ideal for power system maintenance, transformer production and commissioning. Adopting single power input and internal digital combined standard sine wave test source output, it integrates multi-functional testing capabilities including single/three-phase winding test, Z-type, Scott and Anti-Scott transformer test, with a wide turns ratio measurement range of 0.8~10000 and high accuracy (0.1% for 0.9-200). For customers concerned about transformer turns ratio tester price, the product features high cost performance with integrated multi-test functions and reliable quality, realizing one machine for multiple uses and reducing the overall testing equipment investment. Equipped with a 5.6-inch high-definition LCD, it displays test results via digital data and hexagon vector diagrams, and features a blind test function that automatically identifies connection groups without external short-circuit for Y/△,△/Y transformers. The built-in high-capacity rechargeable lithium battery supports over 500 continuous tests after full charge, with a compact size (320mm×240mm×130mm) and light weight (3Kg) for easy on-site carrying and operation. It also has a tapping test function for quick measurement of turns ratio at each tap position, and stores test data for later inquiry, with a built-in printer for on-site result printing, greatly improving the efficiency of transformer turns ratio and phase angle testing.efficiency of transformer turns ratio and phase angle testing.

FAQ
Q: How many continuous tests can the built-in lithium battery support after full charge, and what are the battery maintenance requirements?
A: It supports more than 500 continuous measurements after full charge. It is recommended to charge it daily under normal use, once a month if idle for a long time, with a single charging time of more than 6 hours; do not replace the battery with other types randomly.
Q: What unique blind test function does the tester have, and how to use it?
A: The blind test function requires no manual selection of connection mode and group number; when testing Y/△,△/Y transformers, no external short-circuit is needed, and the instrument automatically switches the connection method according to the selected test content.
Q: Can the tester complete three-phase transformer testing quickly, and how long does it take for a single three-phase test?
A: Yes, it has a high measurement speed, and a single three-phase turns ratio test can be completed within 40 seconds, realizing one-time measurement of three-phase turns ratio, phase angle, error, tap position and other parameters.
