Theory of Ultra-Low Frequency Dielectric Strength Test
Ultra-Low Frequency Dielectric Strength Test is the alternative way for power frequency voltage withstand test. as we know , it is needed huge capacity testing transformer or a resonant transformer for power frequency voltage withstand test to large generator ,cables etc due to larger electrical capacity of insulating layer . The huge equipment not only bulky but also expensive and not suitable for use. The electricity sector makes some test to solve the problems. according to theory and test result from domestic and overseas , 0.1Hz ultra-low frequency voltage withstand test can solve this problems and the advantage is not only got same test results but also the instrument dimensions is small and considerably reduced the weight of it . The capacity of it is 1/500 of tradition way. Greatly simplify testing procedures, That is why commonly used in the developed countries, china 's 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.
Product Introduction
This product combines the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection. human intervention can cared out during the automatic step-up process , mains advantage includes fully electronic ,small sizes and light weight , large-screen LCD ( clear and intuitive ) , printer output test report , easy to use . designed to fully meet the power industry standards .mechanical approach are widely use for modulation and demodulation ultra-low-frequency signals but no standard sine wave , some error of measuring and spark discharge in high-pressure part etc, the products can overcome the shortcoming of above and the following features need to indicate in particular:
