Product Introduction: Our company according to the field voltage transformer testing work, need complex equipment, large volume, heavy weight, high voltage, long preparation time, low efficiency and some hidden dangers of the actual situation. The characteristics of voltage transformer are studied scientifically and systematically, and a scientific theoretical model is established. On the basis of a large number of experiments, the field error comprehensive tester of voltage transformer is developed. It can satisfy the user to measure the error (ratio difference, Angle difference) of voltage transformer. It has the characteristics of high precision, good stability, small volume and light weight.
Product features:
1, meet the requirements of the national regulations in accordance with the voltage transformer measurement 20%-120% of the point error (Angle difference, ratio difference) testing;
2. Complete measurement at one time and display (according to the measurement procedures) the error (Angle difference, ratio difference) of the regulation point under the upper and lower load of the voltage transformer;
3. Complete the measurement and display the error (Angle difference and ratio difference) of the two groups of voltage transformers under any actual load at one time;
4. Test the change ratio and polarity of the voltage transformer;
5. Measure the actual secondary load on site;
6, the instrument can display the test wiring diagram, easy for operators to check wiring;
7, the instrument intelligent prompt wiring error, to ensure the safety of the instrument and the accuracy of detection;
8, the use of small voltage test principle to actively ensure the safety of operators;
9, 320*240 large LCD display, full Chinese interface. Wiring, simple operation, easy to carry;
10, it can store and print all kinds of measurement data, which is convenient for users to inquire;
11, the instrument can be equipped with our company's on-site portable rechargeable test power supply, convenient to take power on site.
