Functions and features
> GTD-61A automatic oil Tan Delta Tester and volume resistance tester oil dielectric loss tester, Highly automatic, temperature rise, dielectric loss measurement and resistance measurement can be completed at one time.
> Medium frequency induction heating and PID temperature control algorithm are adopted. The heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, high speed and convenient control, so that the temperature is strictly controlled within the preset temperature error range.
>GTD-61A automatic oil Tan Delta Tester and volume resistance tester oil dielectric loss tester, Adopting advanced DSP and FFT technology to ensure data stability, accuracy and reliability.
> The internal standard capacitor is SF6 inflatable three-point capacitor.
The dielectric loss of this capacitor is not affected by ambient temperature and humidity, so the accuracy of the instrument is still guaranteed after long-term use.
> Large screen color touch screen, English operation menu, easy to operate.
> It has the tips of opening cover after shut off the high voltage, short circuit of high and low voltage electrode of oil cup to eliminate the hidden danger of safety, ensuring the safety of operator and normal operation of equipment.
> With the real-time clock, the test date and time can be saved, displayed and printed with the test results. The device can display real-time monitoring of the environment.
> Automatically store data and store 100 sets of test data.
> The function of calibration empty electrode cup. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the conditions of the empty electrode cup. The calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
> Having the Wireless transmission function, it is convenient to connect with computer to achieve data transmission and countercharge function.
> The oil can be drained off automaticly without being taken out, it is convenient to clean.
