oil tan delta tester back panel[/caption]ASTM D924 Transformer Oil Dielectric Dissipation Tester is provided by Lucyelec Test Equipment. It's also called High Precision Oil Dissipation Factor Tester or oil tangent delta tester, which is used for testing dielectric dissipation factor (tangent delta value), relative permittivity and DC volume resistivity of insulating liquids. Please contact Lucyelec for more details.
General Descriptions:
Automatic Insulating oil tan delta and resistivity tester,also called High Precision Oil Dissipation Factor Tester or oil tangent delta tester, which is used for testing dielectric dissipation factor (tangent delta value), relative permittivity and DC volume resistivity of insulating liquids.
The instrument is characterized by integrated structure, and integrates the dielectric loss of grease cup, temperature controller, temperature sensor, dielectric loss test bridge,AC test power, standard capacitor, high resistance meter, DC high voltage source and other major components. It is equipped with large colorful touch screen LCD display. The test results can be automatically stored and printed out so that the operator with no professional training will be able to use it easily.
Features and advantages:
1.The test cellused of the three-electrode structure in line with the national standard GB/T5654-2007, with electrode spacing 2mm, can eliminate the effects of the stray capacitance and leakage on dielectric loss test results. The apparatus is equipped with the oil drainage solenoid switch, and we can empty the test cell in case of not removing it and rinse it with the test sample.
2.The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of t non-contact between the test celland the heating body, even heating, fast speed, convenient control, strict control of the temperature within error range of the preset temperature.
3.Internal standard capacitor isSF6 gas-filled three-electrode capacitance, and its capacitor dielectric loss and electrical capacity is independent of ambient temperature, humidity and other effects, so that the instrument accuracy can be ensured even after prolonged use.
4.AC test power supply using AC-DC-AC conversion, effectively avoid the fluctuations in mains voltage and frequency on dielectric loss measurement accuracy effect.Even a generator, the instrument can work properly.
5.Perfect protection function; When there is over voltage、over current or high-voltage short circuit, instruments can quickly cut off pressure, and issues a warning message. When the temperature of the sensor failure or not connected, the instrument will also issue a warning message.
6.There is a temperature limiting relayin the medium frequency induction heating furnace. When temperature above 120 degrees, the instrument frees the relay and stops
7.More convenient the experimental parameter is set. Temperature setting range 0～120℃, AC voltage setting range 500～2000V, DC voltage setting range300V～500V.
8.Using of large-screen LCD display, with backlightand clear display. Friendly interface, simply follow the Chinese menu prompt, enter the command, the instrument can be automatically tested. And automatically store and print test results.
9.Built-in real-time clock, the test dateand time may be saved, displayed and printed with the test results.
10.Calibration functions of cleaned dry cell. The measurement of dry cell’scapacitance and dielectric loss factor can determine its cleaning and assembly conditions. The calibration data is automatically saved and so that it facilitates the calculation of relative permittivity and DC resistivity.
