Calculation of the inducted currents
Calculation of the inducted currents
(OP)
Hello,
I am looking for an approved method to calculate induced current on a metallic armour.
Fiber optic cable is buried in the same trench as power cable (230kV cable) - the distance is about 1ft. The fiber optic cable has armouring (steel wires). I am looking for a IEEE standard or method to calculate induced circulating currents on a fiber optic shield (shield is grounded both ends). Also; to perform calcs to determine standing voltage of one end (if one end is grounded).
thanks.
