Ultra-Low Frequency High Voltage Generator and Its Application in Power Equipment Testing
Abstract
This article mainly discusses the application and technical characteristics of the ultra-low frequency (ULF) high voltage generator in power equipment testing. With the rapid development of the power system, higher requirements have been placed on insulation testing of power equipment. Although the traditional power frequency withstand voltage test is widely used, it may cause damage to the tested equipment; while the DC withstand voltage test is difficult to effectively detect certain types of insulation defects. Therefore, the ultra-low frequency high voltage generator, as a new type of insulation testing method, has attracted much attention due to its characteristics of minimal damage to insulation materials and effective detection of certain types of insulation defects.
