Power distribution on ships
Power distribution on ships
(OP)
Have any of you tried looking at IEC60092 ?!!!
To what extent can you apply it 'as is'? What simplifications do you use :
- what do you do in ring feed situations ?
- do you systematically calculate MV and LV short circuit currents ?
- do you look at the evolution, the asymetric or the symetric short circuit currents ?
- do you calculate the contribution of motors to short circuit currents on the distribution board they are connected to, or to the entire network ?
- how do you check for protection against indirect contact (max cable lengths, earth fault protection, ...) ?
- do you use THAT formula for the calculation of the inductance of a cable !!!!
- are the CENELEC R0064-003 (European calculation guide) simplifications applicable ? If yes, to what extent ?
Thanks for any help on this issue !
