Product Details

Using a transformer ratio bridge to measure the transformer's turns ratio is a cumbersome process with a narrow measurement range, which no longer meets the fast-paced and high-efficiency requirements of modern measurement. To this end, our company has adopted modern electronic technology to develop a new generation of transformer turns 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 character display, menu operation, and a user-friendly interface. The turns ratio and group can be measured in one go. This instrument is an ideal testing device for the power industry.

Product Features:

◆ Automatically measures the connection group.
◆ Automatically performs group transformation.
◆ Automatically switches phase sequence.
◆ Automatically switches range.
◆ Automatically calibrates the meter.
◆ After inputting the standard turns ratio, it can automatically calculate the relative error.
◆ After one measurement is completed, the test voltage is automatically cut off.
◆ Settings and measurement results are automatically saved, and previous data can be viewed.
◆ For measuring on-load tap-changing transformers, only one turns ratio input is required.
