Fult current analysis

Fult current analysis

Fult current analysis

(OP)
hello

im currently doing a project which is "fault analysis on the power system of marine vessels"

because of the inrease in electrical supply, generation will have to increase to meet demand which will cause unaceptable high fault current a low voltage levels in the power network

the area ive started looing into is variying the z% of the lv transformers and analysing whch % will give the lowest fault current while still operating with in spec (Defstan and Stanag)

ive analysed the effect that will have in the steady state ( voltage reduction and recovery times)and transient states(oscillation etc..)

 now im analysing the cost of this against the cost of just upgrading the complex protection circuity

I would love to here your views and made get some pointers of u guys on things that i might have overlooked or not consiered

ps
I`ve heard that the cables have to be extremly secured because at high current the force generated is also high
is this the case?
