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 ：
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 capacitance of some instrument for your reference.

Theory of Ultra-Low Frequency Dielectric Strength Test：
Ultra-low frequency dielectric strength test is an alternative method of power frequency withstand voltage test.As we know, due to the large capacitance of the insulating layer, a large-capacity test transformer or resonant transformer is required to perform power frequency withstand voltage tests on large generators and cables. Huge equipment is not only cumbersome, but also expensive and unsuitable for use.
