Third-harmonic generator manual
three harmonic generator Introduction
According to the national test standards for power transformers and voltage transformers induction test voltage roughly 2-3 times the maximum working phase voltage considerations. As we all know, the transformer at rated frequency, rated voltage, the core approaches saturation, if the employment test frequency power transformer windings being greater than the rated voltage is applied across the test voltage, the load excitation current to increase dramatically, reaching levels not be allowed , from the relationship between the EMF can be seen that in order to apply the test voltage is greater than the rated voltage, which does not saturate the iron core, the method can be used to increase the power frequency, power supply must be greater than the frequency generator.
Use
BYSBF five columns with three-core structure, the magnetic flux density of the core work in the saturation flux density above selection, the opening connected to the secondary winding of a triangle in the fundamental electrical potential (positive sequence vector) vector and a is 0, and two openings terminal should be the same phase 150Hz third harmonic (zero sequence).
