    Abstract - (Show below) - (Hide below)

    IEC 60270:2000+A1:2015 Applies to the measurement of localizedelectrical discharges in insulating media, restricted to only a part of the dielectric under test and only partially bridging the insulation between conductors. The contents of the corrigendum of October 2001 have been included in this copy. This consolidated version consists of the third edition (2000) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.
