Product Description 10kv Tan Delta Capacitance Dielectric Loss Tester for Transformer tangent test Features1. The instrument 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 50Hz power frequency interference on site, so that reliable data can be measured even under the environment of strong electromagnetic interference.3. 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.4, scientific and advanced data management: instrument data can be exported through the U disk, can be in any PC through special software, view and manage data.5. 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.6. Integrated model, with standard capacitor and high voltage power supply, convenient for field test and reduce field wiring.7, 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.8. It has reverse wiring low-voltage shielding function. In the case of 220kV CVT bus grounding, it can measure the dielectric loss of 10kV reverse wiring of C11 without removing wires9. Able to do ac pressure test.It is convenient for PT and CT to do ac pressure withstand test twice and 400V low voltage system to do pressure withstand test.10. It can identify the frequency of external high-voltage power supply from 40Hz to 70Hz, and it is allowed to use power-frequency power supply or serially connected resonant power supply for high-capacity high-voltage dielectric loss test.11, 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.12. When testing CVT, the capacitance and dielectric loss of C1 and C2 can be automatically tested, and the total capacitance and dielectric loss of CVT equipment can be tested.13.Equipped with insulation resistance testing function, avoid repeated wiring, improve testing efficiency.14, the thermal printer can print output, with calendar clock, convenient for users to test report, with U disk output.15, With computer interface.A computer can control 32 instruments, can be integrated into the integrated high voltage test vehicle, to achieve measurement, data processing and report output.16. 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.Overcurrent protection prevents the instrument from being damaged in case of short circuit or breakdown.17, electric shock protection function, when the instrument operator accidentally electric shock, the instrument will immediately cut off the high voltage, to ensure the safety of the test personnel.Technical specification Accuracy Cx±(reading×1%+1pF) tgδ±(reading×1%+0.00040) Anti-interference indexFrequency conversion anti-interference, in 200% interference can still achieve the above accuracy Capacitance range internal high voltage 3pF~60000pF/10kV 60pF~1μF/0.5kV external high voltage3pF~1.5μF/10kV 60pF~30μF/0.5kV resolutionmaximum to 0.001pF, 4 significant digits tgδ rangeNo limitation, resolution 0.001%, capacitance, inductance, resistance can be automatically identified Test current range10μA~5A Internal high voltage voltage setting range0.5~10kV maximum output voltage 200mA voltage lifting modevoltage setting arbitrarialy test frequencysingle frequency set at will( 40-70hz).
