Since Electric Impedance Spectroscopy (EIS) has been widely used to determine physical properties of materials, it becomes necessary to evaluate different error contributions. In this work, it is studied the effect of the current leakage due to the lack of galvanic insulation from sample to ground, which could distort the results. In order to known the effects of ground coupling, an electric equivalent model is developed to distinguish between the contribution of the sample impedance and the stray impedance one. Model values agree with measured ones.
