II Performance
1. The tan delta tester adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss and other parameters. The test result has high precision and is convenient to realize automatic measurement.
2. The instrument adopts frequency conversion technology to eliminate *0Hz power frequency interference on site, so that reliable data can be measured even under the environment of strong electromagnetic interference.
3. Full-touch large LCD, easy to operate.Full touch LCD screen, large full graphics UI, each process is very clear, operators do not need additional professional train and can use directly .The whole process can be measured at the touch of a finger.
4. Data storage: equipped with calendar chip and large-capacity memory internally, it can save test results at any time, view historical records at any time and print out.The current time and storage time can be displayed and printed at any time.
5, scientific and advanced data management: instrument data can be exported through the U disk, view and manage data  through special software from PC.
6. The instrument is easy to operate and the measurement process is controlled by the microprocessor. As long as the appropriate measurement method is selected, the data measurement can be completed automatically under the control of the microprocessor.
7. Integrated model, with standard capacitor and high voltage power supply, convenient for field test and reduce field wiring.
8, the instrument measurement accuracy is high, can meet the oil dielectric loss measurement requirements, so only equipped with standard oil cup, and special test line can achieve oil dielectric loss measurement.
9. It has reverse wiring low-voltage shielding function. In the case of **0kV CVT bus grounding, it can measure the dielectric loss of *0kV reverse wiring of C*1 without removing wires
*0.  Able to do AC voltage withstand test .t.It is convenient for PT and CT to do ac pressure withstand test twice and **0V low voltage system to do pressure withstand test.
*1. It can identify the frequency of external high-voltage power supply from *0Hz to *0Hz, and it is allowed to use power-frequency power supply or serially connected resonant power supply for high-capacity high-voltage dielectric loss test.
*2, with CVT test function, can achieve CVT self-excitation test, can set high voltage/current, low voltage/current four protection limits, to ensure personal and equipment safety.
*3. Equip PC interface. One PC can control *2 pcs of devices. It can be integrated into the comprehensive high voltage test vehicle to realize measurement, data processing and report output
*4, grounding protection function, when the instrument is ungrounded or not well grounded, the instrument will not enter the normal procedure and will not output high voltage
*5. Over-current protection function, the instrument will not be damaged when the test product is short circuit or breakdown.
*6 electric shock protection function, when operator get an electric shock accidentally, the instrument will cut off the high voltage immediately, to ensure operators safety
