HM5001P Portable Transformer Turns Ratio Display Video
Products features
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" 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.

LCD interface
There are nine screens on LCD interface, which includes main menu and eight function interfaces.
1.Main menu interface
As shown in figure 1.
Figure 1. Main menu
When the tester is started up, the main menu will be displayed as shown in figure 1. There are 8 function options, namely parameter setting, three-phase TTR, three-phase turns ratio, single-phase transformer, Z-type transformer, Scott transformer, Anti-Scott transformer, history data, which can be chosen by pressing "↑", "↓", "←", "→", and the chosen item will be displayed highlightedly, then press "Enter" to enter into corresponding function; State parameters is displayed at the top of screen, including program version No.,date, time etc. Voltage amplitude and residual capacity of internal battery are displayed at the top of screen at the same time, in order that operator can observe the state of instrument battery at any time. In case finds battery with insufficient voltage, he can charge it timely; Prompts bar is located at the bottom of screen, which is aimed at providing simple operation prompts to user, so that user can operate it correctly.
