SX-9000D type anti-interference dielectric loss testerDetailed product description：

The SX-9000D anti-interference dielectric loss tester has added the testing function of a capacitive voltage transformer (CVT), which has the advantages of simple operation, automatic measurement, intuitive reading, no need for conversion, high accuracy, and strong anti-interference ability.

Function and Features
There are multiple measurement methods available, including positive/reverse wiring, internal/external standard capacitors, CVT, and internal/external test voltages for measurement. Positive wiring can measure high voltage dielectric loss.  
When measuring a capacitive voltage transformer (CVT), no other external equipment is required, and the internal output self-excited voltage is 6-50V
Built in SF6 standard capacitor, tgδ<0.005%, Less affected by air humidity.  
Good anti-interference effect; It can effectively eliminate the influence of strong electric field interference on measurement and is suitable for strong interference field tests in power stations of 500kV and below.  
When there is a high voltage short circuit or sudden power outage, the instrument can quickly cut off the high voltage and issue a warning message.  
Good measurement repeatability and voltage linearity (measurement accuracy is not affected by voltage)
Integrated structure, moderate weight, easy to carry.  
Large screen with backlit Chinese LCD display for information prompt operation, easy to use.  
The anti-interference dielectric loss tester comes with a printer to save test data in a timely manner.  
Connect the high-voltage cable to the test sample to ensure safety; The instrument is not grounded and the alarm is triggered. The safety measures are complete.
