Automatic oil dielectric loss and volume resistivity tester

Detailed Product Description

Introduction 

The automatic oil dielectric loss and volume resistivity tester conforms to GB/T5654 standard and is used to determine the dielectric loss factor and volume resistivity of insulating materials that are liquid at the test temperature.

It is used to determine the dielectric loss factor and volume resistivity of insulating materials in liquid form at test temperature, including insulating liquids such as transformers, cables and other electrical equipment. Can be widely used in

Electric power, petroleum, chemical industry, commodity inspection and scientific research and other departments.

Characteristic

1. using medium frequency induction heating, room temperature heating to control temperature (90 ℃)

And constant temperature automatic measurement only 15 minutes

2. Measure oil dielectric loss and volume resistivity at the same time or choose one

3. Adopt large screen LCD display, just follow the Chinese menu

prompt, enter the command, the instrument can work automatically

4. With communication function, can configure computer for real-time monitoring.

Dynamic observation of oil dielectric loss value with oil temperature changes and depicted as a graph

5. Automatic display of measurement results, and data printing and saving

6. With over-voltage, over-current, short-circuit protection, and high voltage

indicates, also has the alarm prompt function
