WUHAN HUAZHONG HUANENG HIGH VOLTAGE&TECHNOLOGY DEVELOPMENT CO., LTD.  

Product Name: Vlf High Voltage Generator (with touch panel) Model NO.: HNVLF-1900 Origin: Wuhan Product Description Introduction VLF (Very Low Frequency) hipot Testers are suitable for testing 10KV,35KV power cables, transformers, switchgear, rotating machinery and 300MW power generator, and other electrical apparatus.ParameterSheet 1modelRated voltageOn-load capacityWeightHNVLF-3038C30kV/30mA(peak value)0.1Hz,≤0.5µF~1.1µF0.05Hz,≤0.5µF~2.2µF0.02Hz,≤0.5µF~5.5µFController:4kgBooster:25kgHNVLF-5058C50kV/40mA(peak value)0.1Hz,≤0.5µF~1.1µF0.05Hz,≤0.5µF~2.2µF0.02Hz,≤0.5µF~5.5µFController:4kgBooster:50kgHNVLF-6068C60kV/50mA(peak value)0.1Hz,≤0.5µF0.05Hz,≤0.5µF~1µF0.02Hz,≤0.5µF~2.5µFController:4kgBooster1(30kV):25kgBooster2(30kV):25kgHNVLF-8088C80kV/59mA(peak value)0.1Hz,≤0.5µF0.05Hz,≤0.5µF~1µF0.02Hz,≤0.5µF~2.5µFController:4kgBooster1(30kV):25kgBooster2(50kV):50kgFeatures 1) Placed way: the placement for longitudinal and transverse, especially suitable for field operation and observe. 2) Shockproof protection: internal and external have special damping rubber support foot and protect aluminum boxes, which can effectively slow motion and lifting the bumpy transport the shock. Ensure the device long-term stability and reliability. 3) Parameter display: touch or external mouse LCD interface display system.Can show resonance voltage (namely test before setting goals voltage), test frequency, measure frequency, low-pressure voltage, low voltage electric current, voltage time, over-voltage protection, over-current protection, flash winding protection, phase booster and stage timing, operation mode switch, capacitor, inductance, frequency swap calculation, parameters, still can show inquiry on frequency curve, voltage curve can intuitivey judgment when trials resonance frequency accurately and stability. 4) Parameter Settings: big screen touch LCD backlit and external mouse directly in completing various parameters Settings. The setting of test items, test types, test parameters, frequency, test voltage, test time and other related parameters can be set or selected. 5) Protection function and information clew: having high-pressure over-voltage protection, low-pressure over-current, over-current protection, as well as detuning protection, zero, shem winding protection, emergency stop, undervoltage protection multiple protection function. 6) Automatic voltage function: system according to the test voltage or manually set of automatic tracking and boost results, stable test voltage, voltage stability can amount to 2.5%. 7) Storage measuring data and print.
