Handheld Portable Type Multifunctional Transformer Turns Ratio TTR Tester

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 turn ratio and angle of “Non
integral point”.

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
inputting 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.
