The effect of high field side error fields on H-mode plasmas of different beta as obesrved experimentally is presented. Furthermore the effect of such error fields on L-H transition is shown, alongside with the empirically observed correction field necessary to alleviate the negative effects of the error fields. Using ideal MHD code IPEC, it is shown that the optimal correction observed in the experiment corresponds to the minimization of the coupling of the error field to the core plasma.
