Introduction:

ASTM D924:Standard Test Method for Dissipation Factor (or Power Factor) and Relative Permittivity (Dielectric Constant) of Electrical Insulating Liquids

TP-6100A Insulating oil dielectric loss and resistivity tester is based on ASTM D 924, IEC and GB/T5654-2007 design and manufacturing of ”Liquid Insulating Material Of Relative Permittivity, Dielectric Loss Factor And DC Resistivity Measurements”. Used for measuring the dielectric loss factor and DC resistivity of insulation oil and other liquid insulating medium. 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. The instrument adopts full digital technology and all of the intelligent automatic measurement, is equipped with large screen (240*128) LCD display. Test results can be automatically stored and printed out so that the operator without professional training will be able to use it proficiently.

Functions and Features

1.Grease cup used in line with the national standard GB/T5654-2007 of the three-electrode structure, inter-electrode spacing 2mm, can eliminate the stray capacitance and leakage effects on dielectric loss test results

2.The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of the oil cup and the heating body non-contact, even heating, fast speed, convenient control, strict control of the temperature in the temperature error within the preset range.

3.Internal standard capacitor of SF6 gas-filled three-electrode capacitance of the capacitor dielectric loss and electrical capacity independent of ambient temperature, humidity and other effects, the instrument accuracy is 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 relay in the medium frequency induction heating furnace. When temperature above 120 degrees, the instrument frees the relay and stops heating.

 7.More convenient the experimental parameter is set. Temperature setting range 0～125℃, AC voltage setting range 500～2200V, DC voltage setting range 0～500V.

 8.Using a large-screen LCD display with backlight, 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 date, time may be retained with the test results, display and print.

 10.Air electrode cup calibration function. Measurement of air electrode cup capacitance and dielectric loss factor, in order to determine air electrode cup cleaning and assembly condition. The calibration data is automatically saved, in order to facilitate the calculation of relative permittivity and DC resistivity.

 we are able to greatly extend oil and component life, which will significantly reduce maintenance and down time costs.we are proud to offer our products and services to assist our clients in achieving optimal machine performance.

TOP Oil Purifiers uses single or multi-stage filtration to remove, particulate, free water, and small quantities of dissolved water if necessary. The systems are usually customized to suite the specific customer application. Oil "regeneration", "reclamation", "recycling" are all terms used to describe the process of restoring used, aged, contaminated oils to "like new" reusable condition. The reclamation process removes free water, most dissolved water, dissolved gas, particulate, carbon contamination, acids, oxidation by products, most color bodies, wear metals, and most additive chemicals.

TOP Oil Testers works on the development, production, market, technical and after-sale service for petrochemical analyzers, transformer substation electrical testing equipment and circuit detecting equipment. Main products are water content testers, surface/interfacial tension testers, flash point testers, kinematic viscosity testers, oil acidity testers, insulation oil dielectric strength testers, transformer characteristics testers, relay protection testers, high voltage testing equipment etc.
