Customization XHYS101 Insulation Oil Dissipation Factor and
Resistivity Measuring System
Introduction

Insulation Oil Dissipation Factor and Resistivity Measuring System
DTL, is designed and manufactured based on GB/T5654-2007 of Liquid
insulating material of relative permittivity, dielectric loss
factor and DC resistivity measurements. It is used for measuring dielectric dissipation factor and DC
resistivity of insulating oil and other insulating liquids. The
instrument is characterized by integrated structure, and integrates
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
color screen (800*480) LCD display, 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.
The main functions and features
1. The test cell used 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 cell and the heating
body, even heating, fast speed, convenient control, strict control
of the temperature within error range of the preset temperature.
Internal standard capacitor is SF6 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 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~ 125ºC, AC voltage setting range 500~2000V, DC
voltage setting range 0~500V.
8. Using of large-screen LCD display, with backlight and 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 and time may be saved,
displayed and printed with the test results.
10. Calibration functions of cleaned dry cell. The measurement of
dry cell's capacitance 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.
