Full-Automatic Ratio and Group Tester

Darui Electric recommends:

Product Introduction:

Using a ratio bridge to measure the transformer ratio involves a cumbersome operation process and a narrow measurement range, which no longer meets the fast-paced and high-efficiency requirements of modern measurement. Therefore, our company has adopted modern electronic technology to develop a new generation of YQ-2010 full-automatic ratio and group tester. It is small in size, light in weight, high in precision, and good in stability. It features a large-screen Chinese display, menu operation, and a user-friendly interface. The ratio and group can be measured at one time. This instrument is an ideal testing instrument for the power industry.

Product Features:

◆ Automatic measurement of winding connection group.

◆ Automatic group transformation.

◆ Automatic phase sequence switching.

◆ Automatic range switching.

◆ Automatic calibration.

◆ After inputting the standard ratio, it can automatically calculate the relative error.

◆ Once the measurement is completed, the test voltage is automatically cut off.

◆ Set data and measurement results are automatically saved, and previous data can be viewed.

◆ For measuring on-load transformers, only one ratio input is required.

Product Parameters:

◆ Ratio measurement range: 1—10000

◆ Group: 1—12 points

◆ Accuracy: 1-1000 0.2 class, 1000-10000 0.5 class

◆ Power supply: AC220V ±10%, 50HZ 

◆ Operating ambient temperature: -5℃ ─ 40℃

◆ Operating ambient humidity: ＜85%

◆ Volume: 430×320×215mm3
