HVHIPOT IEC Standards Automatic Transformer Turns Ratio Test Set TTR GDB P Tester

 1. Real three-phase test: single-phase power input, internal digital synthesis three-phase standard sine wave signal source, through high-fidelity power amplifier, produce three-phase test power supply (distortion less than 0.1%, symmetry better than 0.05%) output, The test results have better equivalence, and there is no such phenomenon as misjudgment of the group.
2, powerful: not only single-phase measurement, but also automatic test of three-phase winding, single-phase, three-phase can measure polarity, phase angle, once measured the AB, BC, CA three-phase ratio, The phase angle value, error, tap position, tap value and other parameters can automatically identify the group number.
3. Phase angle measurement function: Accurately measure the phase angle between the high and low voltage sides, and measure the ratio and angle of the non-integral transformer.
4. Hexagon diagram display function: The test results are displayed by numbers and hexagonal vector diagrams, and the transformer connection group is visually seen.
5. Blind test function: no need to select the wiring mode, no need to select the wiring group, measure transformer without external short circuit, and automatically switch the wiring mode according to the selected test content. It is perfectly possible to measure the ratio and group number of a transformer without a nameplate.
6. Tap test: It can quickly measure the ratio and ratio error of each tap changer position. The rated ratio can be input only once, and the ratio error of each tap position can be calculated without repeated input.
7. At the same time, it has two functions: the turns ratio measurement and the running voltage ratio measurement. The running ratio can more accurately reflect the actual value of the voltage ratio in the case of the actual operation of the transformer.
8, good vibration resistance: the use of military connectors enhance the anti-vibration performance.
9, using 5.6-inch high-definition true color LCD screen, display data effects and vector graphics effect is intuitive and delicate.
10. The test source used in this instrument is a digitally synthesized standard sinusoidal digital source with a distortion of less than 0.1%, which is not affected by the quality of the working power supply.
11, easy to carry: small size, light weight.
12, optional high-capacity lithium-ion rechargeable battery, the field can be completed without any power supply, a full can be more than 800 measurements.
