  • 104431810 Impact of Embedded Generation on Voltage

    Powerful springs tension the diverter switch using a motor and quickly release to perform the tap change. The springs ensure that the tap change is completed even if the charging motor were to fail as the spring mechanism over-toggles. Arcing is inevitable but is reduced by insulation in the form of oil or Sulphur Hexaflouride (SF6) gas [14].
