Product Description

XHBB128A
Transformation ratio tester

 

 

 

DescriptionDuring the production process of semi-finished products and finished products of powertransformers, before the newly installed transformers are put into operation and in accordance withthe preventive test procedures of the National Electric Power Ministry, it is required that thetransformers in operation be regularly tested for the turns ratio or voltage ratio. The traditionalvariable bridge operation is cumbersome, the reading is not intuitive, and the necessary conversionis performed. The test result is only a phase change ratio. The automatic ratio change testerovercomes the shortcomings of the traditional turn ratio test. The instrument completes thethree-phase ratio test at a time, and the test speed is fast and the accuracy is high.Features:1). The test range is wide, up to 5000.2).Test speed is fast, 7 seconds to complete the three-phase test3) .Z-connected transformer test.4). The clock and date display even power is off, data storage.5). High and low voltage reverse connection protection function.6). Transformer short circuit, inter-turn short circuit protection.7). Thermal printer output function, fast, silent.8). Equipped with RS232, USB interface, easy to connect to the computer to export data.9). Small size and light weight.Technical data1). Range: 0.9 ~ 50002).
