Project Description
Product Features:
The full three-phase sinusoidal inverter power supply output, the output voltage is automatically adjusted, with soft start and soft stop functions, so the test speed is fast and the accuracy is high.
Three-phase transformer, single-phase transformer, PT, Z-type transformer transformation ratio, group, polarity test function.
It has a blind test function, that is, the transformation ratio and group test are performed when the high and low voltage connection methods are not known.
CT ratio polarity test function.
Angle difference test function for single-phase test
Tap gears can be tested up to 197 gears
In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation and according to the preventive test procedures of the State Grid, it is required to conduct regular turns ratio or voltage ratio tests on the operating transformers. The traditional transformation ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions are required, and the test result is only a phase transformation ratio value.
This transformer ratio tester overcomes the shortcomings of the traditional ratio bridge test. The screen adopts a large-screen high-resolution LCD screen, which is convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and completes three-phase ratio test at one time. , The test speed is fast and the accuracy is high.
The test range is wide, up to 10,000.
High and low voltage reverse connection protection function.
Output short circuit protection function.
Non-power-off clock and date display; data storage methods are divided into local storage and USB storage, of which the local storage can store 500 test data, and the local storage can be transferred to the USB; the USB storage data format is Word format , You can edit and print directly on the computer.
Thermal printer printing function, fast and silent.
Small size, light weight, easy to carry and use.
