Electrical TEST Instruments and Apparatus with high resistance meter

 

The Insulating Oil Dielectric Loss and Electrical Resistivity Tester mainly used for measuring the dielectric loss factor and DC resistivity of liquid medium, such as insulation oil. Etc. The instrument is characterized by integrated structure, and integrates the dielectric loss of test cell, 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 with full Chinese menu, which each step has prompted the Chinese, the test results can be automatically stored and printed output, so that the operator without professional training will be able to use it proficiently.

Key Function And Feature:

  1. The test cell used three-electrode-type structure in accordance with the national standard of GB/T5654-2007, with electrode gap 2mm, can eliminate the effect of stray capacitance and reducing leakage on the dielectric loss test results.
  2. Instruments used medium frequency induction heating, PID temperature control algorithm. The heating method can make the test cell and heated without contact, and uniform heating, fast, convenient control, and make the temperature strictly controlled within the preset temperature range.
  3. Internal capacitor is SF6 gas-filled three-electrode capacitance, its dielectric loss and capacitance is not affected by the ambient temperature and humidity. It can make the instrument accuracy be guaranteed 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.                                                                                                                                      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. 
  6. More convenient the experimental parameter is set. Temperature setting range 0~125℃, AC voltage setting range 500~2200V, DC voltage setting range 0~500V.
  7. Large LCD display with backlight and clear display, Friendly human-machine interface, simply follow the Chinese characters menu prompt, enter the command, the instrument can be automatically tested, and automatically store and print test results.
  8. The instrument comes with real time clock, the test date and time can be saved,displayed and printed with the test results.
  9. Test cell calibration. We can judge the test cell’s cleaning and assembly by measuring electrode capacitance and dielectric loss factor of the test cell. The calibration data is automatically stored, in order to accurately calculate the relative permittivity and the DC resistivity.

  • Instrument instructions and matters needing attention:
  • Be sure to connect the ground cord firmly before start up the equipment, and switch on AC220V power supply.
  • Open protective cover, and take out the test cell;We should shut the protective cover, when heating and testing the dielectric loss.
  • The cover is protective and when you open it, will interrupt the heating and high pressure.
  • During the test, there is high pressure and high temperature. Do not contact the test cell and cable when the power is on and testing.
  • Be careful so as not to sprinkle oil into the test cell receptacle and the side panel when injecting and discharging oil.
  • If there was a crash test, turn the system back on, restart the instrument.
