  • The Most Important Tests For Medium Voltage Metal-Enclosed

    Apr 01, 2020 · The DC hi-pot test is not preferred for testing AC switchgear because the application of DC voltage does not produce similar stress in the insulation system as is produced under operating conditions. Moreover, the DC hi-pot test produces corona and tracking owing to concentration of stress at sharp edges or end points of buses.
