Ultra-low Frequency High Voltage Generator is closer to the actual operating conditions of equipment



The Ultra-low Frequency High Voltage Generator (VLF) is a precision instrument specifically designed for insulation withstand voltage testing of power equipment. It is mainly used to replace traditional power frequency withstand voltage test equipment, solving the problems of bulky equipment and excessive power supply capacity requirements when testing large capacitive test objects (such as long-distance cables and large generators).

In simple terms, its core function is to reduce the test frequency (usually to 0.1Hz), thereby reducing the required test power supply capacity to about 1/500 of the power frequency (50Hz) while ensuring the test effectiveness, making the equipment lightweight and easy to operate on site.
