Abstract
Pad-mounted distribution switchgears are widely used for more than 40 years. This paper review the causes of growing failure rates noted particularly in the last 15 years and review corrective actions being undertaken by Hydro-Quebec in order to reduce this failure rate. Insulation contamination associated with high humidity and condensation is the major cause of failure identified
