Products Introduction
40KV vlf high voltage generator of this product fully complies with the standards of the electric power industry. Mechanical methods are widely used to modulate and demodulate ultra-low frequency signals, but there is no standard sine wave, some errors in high-voltage part measurement and spark discharge. The product can overcome the above shortcomings.
How to choose the suitable products for test ï¼?
Please make sure that the capacitance of test products is below the instrument rated capacitance. The waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.05µF capacitor in parallel to auxiliary output. Below is the capacitance of some instrument for your reference.
VLF high voltage generator 70KV instrument can be widely used in cables, large-scale high-voltage rotating motors, and power capacitors for AC withstand voltage tests. The advantage is that the instrument is small in size, light in weight, and large LCD display.

After years of research and development our company has successfully developed battery charge and discharge tester which is highly intelligent and accurate with its proprietary technology. This tester can be used as a discharge load in the off-line state of the battery and realize constant discharge of the set value through continuous control of discharge current. During discharge when the terminal voltage of the battery or the voltage of the single battery falls to the set lower limit or the set discharge time reaches or the set discharge capacity the instrument will automatically stop discharging and record all valuable and continuous real-time data of the process.
Battery charge and discharge tester system the voltage monitoring information of single battery is simple safe and accurate with wireless relay access.
Battery charge and discharge tester it has a very friendly man-machine interface which can not only complete all kinds of settings and data query under the prompt of menu but also save the process data of discharge in the memory of the equipment transfer to the U disk through the data interface and analyze the data through the special software of the upper computer to generate the required curve and report.
Battery charge and discharge tester there is perfect protection function not only sound light warning but also a clear interface tips.
This instrument is developed and designed according to the national power industry standard DL/ t506-2007 "insulation gas humidity measurement method for sulfur hexafluoride electrical equipment" and adopts the imported high-precision dew point sensor and new digital circuit control technology. It is a high-precision intelligent instrument to measure the trace moisture content in SF6 gas.
