Abstract

Superimposed voltage waveforms may result in electrical stresses in dielectric materials not anticipated for. Non-intrusive  ethodologies to observe these events, both capacitively and inductively, are discussed. This paper presents two examples where complex waveforms arise from energizing and de-energizing inductive loads. Case I: A compensation coil connected through overhead lines showed high overvoltage levels when being energized by means of a SF6 switchgear. Case II: A compensation coil connected via a power cable with a vacuum switchgear experienced high overvoltage levels from recurrent restrikes during its de-energization.
