In this article, we discuss a method to identify whether the observed perturbation in toroidal plasmas is a quasi-electrostatic perturbation or not. A criterion is derived based on the observed data of plasma deformation and external magnetic perturbations. This result can be applied to the study of properties of quasi-modes, which have been observed in toroidal plasmas.
