GDB-P Three Phase Transformer Voltage Ratio Tester Turns Ratio TTR Meter
Product Description
GDB-P
Three Phase Transformer Voltage Ratio Tester Turns Ratio TTR Meter
Main Features
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.
5 inch TFT color LCD screen, intuitively display data and vector diagram.
3 phase testing at the same time. Single power input, with internal digital combination standard sine wave test source. It generates 3 phase test power output, the test result has better equivalence.
It can conduct single-phase measurement and three-phase winding automatic test. Turn ratio, phase angle, error, tapping position, tapping value of AB, BC, CA three phase can be measured for once. It also can identify connecting group number automatically.
Accurately measure phase angle between high voltage side and low voltage side. It also can measure turns ratio and angle of “Non-integral point” transformer.
Testing results can be displayed by digit and hexagon vector diagram, that the connection group can be seen intuitively.
No need to select connection method or group. When measuring Y/△, △/Y transformer, no need to short circuit externally. Connection method can be shifted automatically according to selected test content. Measure turns ratio and group for the transformer without nameplate.
TTR and TTR error in the position of each tapping switch can be measured quickly. Just input rated TTR once, instead of inputting over and over again, TTR error at tapping position can be calculated.
With functions of turns ratio measurement and voltage TTR measurement.
With good anti-vibration performance.
Standard sine wave digital source, distortion degree is less than 0.1%.
Small size and light weight, easy to carry.
