N2 - The influence of relative air humidity on the surface charge decay on epoxy resin insulators initially charged by DC corona and on their surface resistivity is investigated at room temperature. It has been observed, that surface resistivity of the epoxy resin insulators decreases significantly at higher relative humidity. Thus, at higher relative humidity surface charge decay is dominated by electric conduction along the insulator surface. This effect has been verified by both, measurement and simulation of the surface charge decay.
