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.
