INTRODUCTION

During the production process of semi-finished products and finished products of power transformers, before the newly installed transformers are put into operation and in accordance with the preventive test procedures of the National Electric Power Ministry, it is required that the transformers in operation be regularly tested for the turns ratio or voltage ratio. The traditional variable bridge operation is cumbersome, the reading is not intuitive, and the necessary conversion is performed. The test result is only a phase change ratio. The automatic ratio change tester overcomes the shortcomings of the traditional turn ratio test. The instrument completes the three-phase ratio test at a time, and the test speed is fast and the accuracy is high.

MAIN FEATURES

1,Instrument internal adopt precision three-phase inverter measurement power supply instead of the single-phase mains supply as measuring voltage, which eliminate the harmonic effect of the main voltage , more accuracy. If the working power supply is generator and its without any effect.

2, Adopt 3 phase output voltage,3 phase input voltage and 3 phase measuring at the same time, can very easily automatic identification of transformer connection group 0 -11.

3,Suitable for various of transformers, with the function of testing the Z type transformer.

4,Using precision three-phase inverter power supply, has the high and low voltage reverse connect protection and transformer inter-turns short circuit protection, tap-changer protection and output short circuit protection functions, increase the stability of instrument.

5,After inputting the rated parameters, can automatic measure transformer turns ratio, error and tap-changer points, especially for asymmetric tap-changer points, also can accurately test the position of the transformer tap-changer, can measure up to 99 points of tap-changer

6,With 65K True Color Module LCD display, each operation step with English prompt, and the operation can be completed just by prompt and no need of manual.

7,With Micro-printer ,USB and RS232 interface.

8,With sealed water-proof and shock-proof sturdy hand-case, be suitable for field testing.

7,Small size and light weight
