    Abstract: The structure of the induced voltage test model for low frequency transients is described and
presented from its components (generator, auxiliary and power transformer). The performed test procedures
are perfomed to estimate the model parameters along with the topology of their connection. Finally, the model
is implemented in the transient analysis software ATP and a frequency response of the test is obtained. This
allows to identify the critical frequencies that cause resonant states and cause over voltage during the test which
facilitates the establishment of application of safety criteria for both operators and the equipment.
