Anti Interference LCD Display Dielectric Loss Tester with CVT testing function

JSY-03 fully automatic anti-interference dielectric loss tester

1.Product introduction

The JSY-03 dielectric loss tester breaks through the traditional bridge measurement method by adopting variable frequency power supply technology, utilizing single-chip microcontrollers and modern electronic technology for automatic frequency conversion, analog-to-digital conversion, and data processing; Achieve strong anti-interference ability, fast testing speed, high accuracy, fully automatic digitization, and easy operation; The power supply adopts a high-power switching power supply, which outputs pure sine waves of 45Hz and 55Hz, automatically pressurizes, and can provide a voltage of 10kV; Automatically filter out 50Hz interference, suitable for on-site testing with high electromagnetic interference in substations and other areas. Widely applicable for dielectric loss measurement of transformers, transformers, bushings, capacitors, lightning arresters and other equipment in the power industry.

2.Features

1. The instrument adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss, and other parameters. The test results have high accuracy and are easy to achieve automated measurement.

2. The instrument adopts frequency conversion technology to eliminate on-site 50Hz power frequency interference, and reliable data can be measured even in strong electromagnetic interference environments.

3. Use a full touch large LCD display, easy to operate. Full touch LCD display screen, super large full graphics operation interface, every process is very clear and clear, and operators can use it without additional professional training. The measurement of the entire process can be completed by lightly touching.

4. Data storage: Equipped with a calendar chip and a large capacity memory, it can save detection 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 data management: Instrument data can be exported through a USB flash drive and can be viewed and managed on any PC through dedicated software.

6. The instrument is easy to operate, and the measurement process is controlled by a microprocessor. As long as a suitable measurement method is selected, data measurement can be automatically completed under the control of the microprocessor.

7. Integrated model, equipped with standard capacitors and high-voltage power supply, facilitates on-site testing and reduces on-site wiring.

8. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only standard oil cups and dedicated testing lines need to be equipped to achieve oil dielectric loss measurement.

9. It has the function of reverse wiring low voltage shielding. When the 220kV CVT bus is grounded, C11 can be measured for 10kV reverse wiring dielectric loss without disconnecting the wire.

10. Able to conduct AC withstand voltage tests. Convenient PT and CT secondary AC withstand voltage test, 400V low-voltage system withstand voltage test.

11. Able to identify external high-voltage power sources with frequencies ranging from 40Hz to 300Hz, allowing for high-capacity high-voltage dielectric loss tests using power frequency or series resonant power sources.

12. Equipped with CVT testing function, it can achieve self excitation testing of CVT, and can set four protection limits: high voltage/current and low voltage/current, ensuring personal and equipment safety.

When testing CVT, not only can the capacitance and dielectric loss values of C1 and C2 be automatically tested, but also the total capacitance and dielectric loss values of CVT equipment can be tested

The 14 comes with a thermal printer that can print and output, and comes with a calendar clock, making it easy for users to print test reports. It also comes with a USB flash drive for output.

15. With computer interface. A computer can control 32 instruments and can be integrated into a comprehensive high-voltage test vehicle to achieve measurement, data processing, and report output.

16. Grounding protection function: When the instrument is not grounded or has poor grounding, the instrument will not enter the normal program and will not output high voltage. The overcurrent protection function ensures that the instrument is not damaged in the event of a short circuit or breakdown of the test object.

Electric shock protection function. When the instrument operator accidentally gets an electric shock, the instrument will immediately cut off the high voltage to ensure the safety of the testing personnel.
