HV Cables - Single core HV cables (induced EMF / Circulating currents)
HV Cables - Single core HV cables (induced EMF / Circulating currents)
(OP)
I am currently looking at a design using single layer spaced cables installed on cable ladder, spaced De apart based on IEC 60502, the standard refers to cables earthed at each end (solidly earthed).
The induced voltage when using 300mm Cu/XLPE/AWA/PFC cables to BS6622/7835 equates to 15.3V (Phases A & C) and 11.92V (Phase B)
What is the relationship between the load current of 656A, the sheath resistance and the armour resistance
My mistake has been to assume I = Induced EMF / Sheath resistance ??

IEEE Std 575-2014 IEEE Guide for Bonding Shields and Sheaths of Single-Conductor Power Cables Rated 5 kV through 500 kV Annex D [informative] Calculation of induced voltages.
D.2 Voltage gradients induced in the cable shield/sheath.
In D.2.1 General case of any cable formation. The Ea, Eb, Ec induced voltage is direct proportional with the current Ia, Ib, Ic flowing in the main circuit.

I am currently trying to obtain either IEC 60287 or the IEEE 575-2014 to progress
