KESBP Series Triple Frequency Generator
(Frequency Multiplication Induced Voltage Withstand Test Device)

I. Product Overview:
       The KESBP series triple frequency generator is used for test objects such as power transformers and voltage transformers. In addition to applying external power frequency high voltage tests to the main insulation of fully insulated transformers, it also performs induced high voltage tests on the longitudinal insulation of transformers and the main insulation of semi-insulated transformers. 
       According to national test standards, the induced test voltage for power transformers and voltage transformers is generally considered to be 2-3 times the working phase voltage. As is well known, under rated frequency and rated voltage, the transformer core approaches saturation. If a power frequency supply is used to apply a test voltage higher than the rated voltage across the windings of the test transformer, the no-load excitation current will increase sharply to an unacceptable level. From the relationship of induced electromotive force, it can be seen that to apply a test voltage higher than the rated voltage without saturating the core, the method of increasing the power frequency can be adopted, necessitating the use of a frequency multiplication power generator.
