  • Product Features

1. High efficiency and fast DC power supply is adopted, and the opening voltage can reach 24V, which can quickly charge and discharge the transformer winding.


2. The test precision is high. The instrument adopts 16 bit high-precision AD converter with CPU and DSP (digital signal processing) chip, which effectively ensures the measurement accuracy and anti-interference ability.


3. Each test can display and print all the test data of the three-phase winding of the transformer, automatically calculate the three-phase unbalance rate, and display and print the resistance converted to the rated temperature.


4. It has perfect overcurrent protection and wiring inspection functions.


5.320x240 large screen, high brightness liquid crystal display, full Chinese character menu and operation tips to realize friendly man-machine dialogue. It is equipped with a real-time electronic clock to automatically record the date and time of the test, which is conducive to the preservation and management of the test results.


6. The data has the functions of power down storage and browsing, and can store 1000 groups of experimental results.


7. it has sound and LCD indicating discharge alarm, clear discharge index and reduced misoperation.
