DX8000 Off Frequency Dielectric Loss Tester

DX8000 Off Frequency Dielectric Loss TesterIt is a high-precision testing instrument used for testing the dielectric tangent and capacitance of various high-voltage power equipment on site or in laboratories, such as power plants and substations. The instrument is an integrated structure with a built-in dielectric loss testing bridge, a variable frequency voltage regulating power supply, a step-up transformer, and SF6 high stability standard capacitors. The high-voltage source for testing is generated by the inverter inside the instrument and is used for testing the test sample after being stepped up by a transformer. The frequency can be changed to 50.0 Hz、47.5Hz\\52.5Hz、45.0Hz\\55.0Hz、60.0Hz、57.5Hz\\62.5Hz、55.0Hz\\65.0Hz， By using digital notch technology, the interference of power frequency electric fields on testing is avoided, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also applicable to situations where a generator is used for power supply testing after a complete power outage. This instrument is equipped with an insulating oil cup and a temperature control device to test the dielectric loss of insulating oil.

DX8000 Off Frequency Dielectric Loss TesterIt mainly has the following characteristics:

Large LCD Chinese display

Easy to operate, the instrument is equipped with a full touch LCD display screen and a super comprehensive touch operation interface. Each process is very clear and understandable, and operators do not need additional professional training to use it. With just a gentle click, the entire measurement process can be completed, making it an ideal intelligent dielectric loss measurement device at present.

Massive storage of data

The instrument is equipped with a calendar chip and a large capacity memory, which can store 200 sets of data. It can save the test results in chronological order, view the historical records at any time, and print and output them.
