The utility model relates to a special flickering voltage output equipment for examineing and determine electric energy quality test equipment, including signal source, processing apparatus, digital analog device, power amplifier, transformer and voltage output port, digital analog device connects signal source, processing apparatus and power amplifier respectively, and power amplifier is connected to the transformer, and connects the electric energy quality test equipment who is examined and determine through the voltage output port, the constant amplitude sinusoidal signal of digital analog device received signal source follower and processing apparatus be according to predetermineeing output flickering signal to power amplifier behind the default values who changes output, and power amplifier receives flickering signal to the transformer after output is enlargied behind the flickering signal, and output flickering voltage to electric energy quality test equipment behind the flickering signal after enlargeing is received to the transformer. Flickering voltage exports electric energy quality test equipment to as standard signal, can be used to the check -up to electric energy quality test equipment.
