Range Conversion
Overloading
D = 27648 x I / 20
I = D x 20 / 27648
Nominal range
Overloading
D = 27648 x (I – 4) / 16
Nominal range
I=( D x 16 / 27648 )+ 4
Underloading
Overloading
D = 27648 x U/10
I = D x 10 / 27648
Nominal range
Overloading
D = 27648 x U / 10
Nominal range
U = D x 10 / 27648
Underloading
Overloading
D = 27648 x (U – 2) / 8
U = D x 8 / 27648 + 2
