I. Introduction:
This Ultra Very Low Frequency Test Equipment combines the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection.Human intervention can carried out during the automatic step-up process.
The VLF Test Equipment is suitable for testing cables, transformers, switchgear, Rotating machinery, and other electrical apparatus.
★ Small sizes and light weight
★ large-screen LCD (clear and intuitive)
★ Test report can be printed out with inbuilt printer
★ Meet the power industry standards
★ Easy operation
III.Main Features
★ Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
★ Over-voltage protection: the hipot test equipment will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.
★ Over-current protection: design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side.The VLF Hipot Test Equipment will be shut down for protection and the action time is less than 20 ms when the current of low-voltage sides exceeds reacted current.
★ High-voltage output protection resistor design in the body boost and additional outside resistor is not needed.
★ Closed-loop negative feedback control circuit of high and low voltage.
