Products Introduction

VLF high voltage generator 60KV.The capacity of it is 1/500 of traditional way. Greatly simplify testing procedures, That is why commonly used in the developed countries, china ministry of electric power entrust Wuhan high voltage research institute to drafting 35Kv and below XLPE insulated power cable ultra-low frequency (0.1Hz) voltage withstand test methods for promoting this approach. The instrument is developed according to China's made of this need. It can be widely used in cable, large-scale high-pressure rotary motor, power capacitors into AC voltage withstand test.

Precautions

1.Please use the STOP button and discharge by rod then shut down the power if you need to discontinue the machines which in the high pressure conditions.Otherwise it will damage the instrument!

2.Please operation it according to the screen instructions.

3.It is a normal phenomenon to see small amount of oil spill after boosting the pressure because the insulating oil in the booster is full, besides, it will not affect your use.

4.When carrying out 10KV cable test, one-phase test is strongly suggested. The voltage shall be 18KV and the frequency shall be 0.1Hz 0.05Hz 0.02Hz 0.01Hz. The manual said load capacity is the theoretical value, the scene 10KV cable length can reach 3-20km.

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.
