Very Low Frequency Tester for High Voltage Cable BVLF-90KV
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 Very-low-frequency tester, which the 0.1Hz Very-low-frequency technology is the latest technology, the technology recommended by the International Electro technical Commission.
BVLF series of Very-low frequency high voltage generator using self-developed core products of the latest American technology, it overcomes many shortcomings of 0.1Hz mechanical withstand voltage test equipment (see Table 1),Better performance (see Table 2) compared with a similar variety of withstand voltage test equipment, And performance and low cost is far better than similar imported products, Particularly suitable for large electrical equipment insulation equivalent capacitance (for example: power cables, power capacitors, medium and large generators and motors, etc.) withstand voltage test.
- Advanced technology: the use of digital frequency conversion technology, microcomputer control, boost, buck, measurement, protection, fully automated testing process.
- Easy to operate: the wiring simple, fool type operation.
- Comprehensive protection: multiple protection (high and low pressure side of the overvoltage protection, overcurrent), fast response action (action time≤20ms),safe and reliable instrument.
- Safe and reliable: low-voltage connection of the controller and high-voltage generator,photoelectric control, safety and reliability.
- Using high and low voltage closed-loop negative feedback control circuit, the output is not capacity effect.
- Configuration is complete: the touch screen, LCD display, automatic storage, automatic printing,supporting the PC software.
- Test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, the test range
- Small size, light weight: very conducive to outdoor jobs.
- USB2.0 data interface to download data quickly and easily.
