Click to download: MEWOI-LX5265 3-Phase Transformer turn ratio tester User Manual
INTRODUCTION
MEWOI-ZCB2000T intelligent tester of Transformer Ratio and Connection Groups adopts popular ARM processor, 168M frequency, 128M memory available to be extended to 4G memory card. The LCD screen adopts 5-inch high-definition color touch screen, combined with emwin display, making the tester interface simple and user-friendly in full touch screen and non-keyboard operation. The tester supports database and can be exported from the USB drive or through the data cable to the background computer. |
MAIN FEATURES
1,The tester makes automatic measurement with no need to set any parameters and automatically completes the three-phase ratio and connection group measurements with easy operation. All you need to do is to press a button. |
2, The tester measures three-phase and single-phase transformer ratios automatically, and calculates the ratio error. |
3,Built-in three-phase signal source, which can measure the transformation ratio of transformers of various connection groups such as Y / y, Y / d, D / y, D / d. |
4, It can measure the label and polarity of the transformer connection group, and display the primary and secondary wiring vector diagrams, which are intuitive and clear; the instrument has a self-calibration function, which can judge the test line or the instrument failure based on the self-calibration results. |
5, The tester can track the transformer on-load tap-changer position automatically,and indicate the current tap point automatically. |
| 6,The tester can display a transformer’s first and secondary voltage Oscillograms and phase relationship. It can measure transformer’s first and second harmonic voltages, to facilitate the analysis of transformer failure. |
7, The tester is with CT, PT ratio, polarity testing function |
| 8, The tester has perfect and reliable automatic protection, to ensure the intactness of the tester under abnormal conditions. |
| 9,The tester has small size and light weight. It makes accurate measurement at fast speed (about 3 seconds to complete the test). |
| 10,The tester is available to store and print all the test results. It has Built-in 128M memory (extendable to 4G memory card), available to export the database by USB, or upload to computer. The database supports excel spreadsheet opening. |
| 11,The tester has7-inch true color touch screen operation, emwinGUI interface and support English input, which is easy and convenient. It also has no power-down |
| 12,The tester support on-site record print by Bluetooth or serial printer. |
