This formula is wide-known as that for the catenary curve. Cable sag (h) is value of cable form equation for point l/2 (formula 12), where l is the straightline distance between the position transducer and the application (Figure 1). For cable length, we will use the formula for the length of the catenary curve (formula 13).
