Insulating Oil Dielectric Loss Automatic Tester

详情

1. Summarization

This instrument is used to judge the degree of aging by testing the dielectric loss of insulation oil. The resistivity of insulation oil can also be tested.
Dielectric loss factor is very sensitive to aging product. When the aging degree is little, it is difficult to notice through common chemical method. Dielectric loss factor can be used to identify it apparently.

The instrument is produced according to national standard GB/T***4.
The instrument adopts the advanced technology, such as wavelet analysis of digital technology and automatic intelligent testing, to test dielectric loss. The instrument has built-in sample cup, temperature control, digital bridge, sophiscated high-resistance meter, AC-DC power. It has features such as easy operation, stability and good repeatability. Testing results can be displayed, printed and stored automatically.

2. Features & Technical Specification

(1) Features

1. Temperature is raised quickly, steadily without overshoot by artificial intellegence netural network controlling technoloty.

2. Precision processing elcotrode of new technology cup is applied.

3. The advanced technology, such as wavelet analysis of digital

Technology and high precision resistance meter, guarantees the testing results of high precision and good repeatability.

4. The operation is easy and of high automation. It can automatically test, calculate, store and type the results. The real-time date, time and day are displayed. **0 groups of data can be stored.

5. Big screen monitor is applied. Convenient new interface, which is close to WINDOWS, is adopted to accord with computer operation habit.

6. Overcurrent, over voltage, electric shock protection, safe operation by humanized design.
