Integrated 30kv Ultra Low Frequency High Voltage Set Generator Electronic Vlf Test

Product Description

Product overview:

The ultra-low frequency insulation withstand voltage test is actually an alternative method to the power frequency withstand voltage test. When conducting power frequency withstand voltage tests on large and medium-sized generators, motors, power cables, and other test samples, large capacity test transformers or resonant transformers are required due to the large capacitance of their insulation layers. These huge devices are not only bulky and expensive, but also very inconvenient to use. In order to solve this contradiction, the international community generally adopts the method of reducing the test frequency, thereby reducing the capacity of the test power supply. From years of theoretical and practical experience both domestically and internationally, it has been proven that replacing the power frequency withstand voltage test with a 0.1Hz ultra-low frequency withstand voltage test not only achieves the same equivalence, but also greatly reduces the size and weight of the equipment. In theory, the capacity is about one fifth of the power frequency, and the operation is simple. This is the main reason why this method is widely adopted.

The new generation of integrated 0.1Hz ultra-low frequency high voltage generator developed by our company adopts the latest power electronic components and ARM7 microcontroller technology, further reducing the size and weight of the equipment. It is easy to operate and has more stable performance, overcoming the disadvantages of short service life, high failure rate, and large volume of the first generation mechanical booster. Through years of practice, feedback from a large number of users has shown that this series of ultra-low frequency high-voltage technology is leading in the country and has the highest cost-effectiveness!
