MSVLF-80kV 1.1uFultra low frequency generator

30kV/40kV/50kV/60kV/80/90kV

This device is particularly suitable for withstand voltage testing of electrical equipment with large equivalent insulation capacitance (e.g., power cables, power capacitors, large and medium-sized generators and motors).

1. Advanced technology: Adopts digital frequency conversion technology and microcomputer control; the entire testing process, including voltage boosting, voltage reduction, measurement, and protection, is fully automated.
2. Easy operation: Simple wiring and convenient use.
3. Comprehensive protection: Multiple protection features (overvoltage protection, high and low voltage side overcurrent protection) with rapid response (action time ≤10ms); the instrument is safe and reliable.
4. Safe and reliable: Low-voltage connection between the controller and high-voltage generator; photoelectric control ensures safe and reliable operation.
5. Adopts a high and low voltage closed-loop negative feedback control circuit, resulting in no capacitive rise effect in the output.
6. Complete configuration: Capacitive touch screen, LCD Chinese character display, automatic storage, and automatic printing.
7. Wide test range: Multiple frequency options of 0.1Hz, 0.05Hz, and 0.02Hz provide a wide test range.
8. Small size and light weight, especially suitable for outdoor work.
9. English and Chinese language switching function.
10. Performance comparison of the ultra-low frequency 0.1Hz test device with other withstand voltage test equipment.
