Insulation Oil Dielectric Loss & Resistivity Tester

Automatic precision oil dielectric loss tester is used for measuring dielectric loss factor and dc resistivity of insulating liquid dielectric such as insulating oil.The instrument is equipped with a 5.7-inch TFT pure color LCD touch screen and a English menu. The test results can be stored and printed out automatically. The operator can use it skillfully without professional training.

Applications

1.Power Transformer Condition Monitoring：Regular testing of insulating oil in power transformers (transmission, distribution, and generator step-up units).
2.High-Voltage Laboratory Quality Control：Testing new insulating oil batches before filling transformers or switchgear.
3.Circuit Breaker and Switchgear Maintenance：Analyzing oil in oil-filled circuit breakers and switchgear.
4.Cable and Capacitor Manufacturing：Quality control of insulating oil used in high-voltage cables and capacitors.
5. Industrial Plant Predictive Maintenance：Testing insulating oil in critical plant assets (e.g., furnace transformers, rectifiers).
6.Renewable Energy Substations：Maintaining transformers in wind and solar farms.
7.Railway and Traction Power Systems：Testing oil in traction transformers and railway substation equipment.
8.Insurance and Risk Assessment：Evaluating transformer health for insurance underwriting or asset transactions.

(1)Oil cup of the accord with national standard GB/T5654-2007 three electrode type structure, the electrode spacing 2 mm,Can eliminate the stray capacitance and xie's influence on the dielectric loss test results.

(2)Instrument by medium frequency induction heating, PID temperature control algorithm.The heating mode with oil cup with non-contact heating body, heat evenly, high speed, convenient control,Make temperature strictly controlled within the preset temperature error range.

(3)Internal standard capacitor for SF6 inflatable three pole type capacitor, the capacitance of the dielectric loss and capacitance is not affected by environmental temperature, humidity,The instrument accuracy after long time use is still guaranteed.

(4)Test AC power supply adopts AC - DC - AC conversion method,Effectively avoid the mains voltage and frequency fluctuations impact on dielectric loss test accuracy,Even if is a generator, the instrument can also run correctly.

(5)Perfect protection function.When over voltage, over current, high voltage short circuit,Instrument can quickly cut off the high pressure, and send out a warning message.. When the temperature sensor failure or not connected, the warning information.In the medium frequency induction heating furnace with finite temperature relay,When the temperature over 120 degrees, the relay release, stop heating.

(6)Parameters setting is convenient.Temperature set range of 40 ~ 120 ℃,Ac voltage setting range200 ~ 2200 v,0 ~ 500 v dc voltage setting range.

(7)Adopted the pure color TFT LCD touch screen display, show clear.Simply set, the instrument can automatically test.And automatic storage and print the test results.

(8)Built-in real-time clock, the test date, time may be retained with the test results, display and print.

(9)Empty cup electrode calibration function.Measure the empty cup electrode capacitance and dielectric loss factor, cleaning and assembly of electrode to determine empty cup.Calibration data is automatically saved for rel
