Reference: Prevention of Fire Accidents in Crude Oil Electric Dehydration (Desalination) Unit P3 (23)
According to formula E x =U/(r x ln(r two /r one ))
Where, E x Is the inner diameter distance of the rod, r x Electric field strength at, V/cm; U is the voltage borne by the insulating rod, V; r x Is the radial distance from the center of the insulating rod, cm; r one Is the radius of conductive core, cm; r two Is the radius of insulating rod, cm;
When r x =r one E value is the maximum, that is, the electric field strength in the insulating rod next to the conductive rod is the maximum; Maximum field strength of insulating rod E max =U/(r one ln(r two /r one ))
