Electric field measurements around a metal oxide surge arrester

Aim of the current work is the experimental study of the electric field distribution around a medium voltage metal oxide gapless polymeric housing surge arrester, since the study and the knowledge of the electric field around an arrester can be useful for diagnostic tests and design procedures. The measurements were carried out, using two appropriate calibrated field meters. The results are accompanied with their total uncertainties, which were computed using the obtained measurements and data from the calibrations certificates.
