Partial discharge and corona are crucial early indicators of high-voltage insulation weakness, yet they are very different phenomena. In part one of a new series, Marius Grisaru explores the foundational physics of discharge mechanisms, from internal voids to surface tracking. Discover why understanding these fundamental differences is key to making sound asset management decisions.
