Very Low Frequency Withstand Voltage Test Equipment VLF Cable Tester 80KV




The third generation SVLF series Ultra-Low-Frequency High Voltage Generator

Product brief;
The high-voltage Withstand Test of the electrical equipment is one of the most important projects under The insulation preventive test. Withstand Test can be divided into the AC voltage test and DC voltage test. AC voltage test can use Power frequency, Frequency conversion and 0.1Hz ultra-low frequency test, which the 0.1Hz ultra-low-frequency technology is the latest technology, the technology recommended by the International Electro technical Commission.

After years of independent research and development, our company's core products, the third generation of SVLF series ultra low frequency high-voltage generator was born. The third generation SVLF series ultra low frequency high-voltage generator will usher in a new era of domestic ultra low frequency high-voltage generator technology development, our company in the field of ultra low frequency 0.1Hz control technology has reached the international advanced level. Especially suitable for insulation equivalent capacitance larger electrical equipment (eg:power cables, power capacitors,medium and large generators and motors, etc.) pressure test.

The third generation of advantages:
1. Waveform without distortion: Standard sine wave output.
2. Strong load capacity: load capacitance to meet the rated capacity(0.1Hz≥ 1.1uF, 0.05Hz≥ 2.2uF, 0.02Hz ≥ 5.5uF).
3. Little impact pulse current: Cycloconverter pulse current generated little impact on the grid.
4. Strong EMI immunity: During the test controller is stable and reliable.
5. Simple operation: Capacitive screen operation, simple and convenient.

Performance Characteristics;
1, Advanced inverter technology: Digital AC-AC inverter technology, advanced software closed-loop control, precise standard output without distortion sine wave, fully automated testing process.
2, Display: The 7 'capacitive touch screen, the screen displays real-time measurement data and the output waveform.
3, Comprehensive protection: high, low pressure side of the overvoltage and overcurrent protection, rapid response action (action time 10ms).
4, Simple operation: simple wiring, fool type operation.
5, Safe and reliable: the controller and the high voltage generator connected to the low pressure, photoelectric control, safety and reliability.
6, The high and low voltage closed-loop negative feedback control circuit, the output can not rise effect.
7, Test range: 0.1 Hz, 0.05Hz and 0.02Hz multi frequency selection, large measuring range.
8, Printer: print the test results.
 Small size, light weight: very conducive to outdoor work.
 Communication interface: USB2.0.
 Software: Equipped with specialized SVLF ultra low frequency high-voltage generator software, can be tested by software, and the data query and print statements.
