  • The Most Important Tests For Medium Voltage Metal

    Apr 01, 2020The DC hi-pot test is normally not made for AC electrical switchgear and therefore may be considered only when AC hi-pot cannot be performed. The hi-pot testing of switchgear involves testing of the circuit breakers and switchgear buses separately. This is a major test and determines the condition of the insulation of the switchgear assembly.

  • Safety by design: solid insulated technologies challenge

    Assuming application of 10 MVA distribution transformers as shown in Fig. 1, the 4.16 kV switchgear interrupting rating would need to be 10 MVA/(1.73 X 4.16 kV)/0.0575 = 24.1 kA. Both are significant interrupting ratings for this class of switchgear. Historically, SF6 has been applied by utilities in high- voltage systems above 38 kV.
