power suplly with N & PE
power suplly with N & PE
(OP)
how can we produce N (neutral) & PE (potential earth in the three pahse system. I got one panel eqpt needs 3 phase power supply 400 v(l1,L2,L3) and N, PE. these N & PE going to control circuit. Can I use Neutral of main generator set for N, how about PE? The terminal block board has 5 for power supply input namely: L1,L2,L3,N,PE. We don't know where we can take these (N & PE)pls give me some advise. this is for the ship. thank you.






RE: power suplly with N & PE
"PE" means the protective earth and will not be carrying current at normal conditions. This cable will be the return path during faults to ground.
Both however are connected to the neutral point of the 3-phase transformer / generator and care is taken to indentify each cable on a cable run. Your equipment is designed for 5-wire, 3-phase(PE and N separate).
Hope this helps.
RE: power suplly with N & PE
thanks for your info. it's really a big help. Is the L to N has voltage? Iwas thinking that this N is just floating. Can we connect N from Y connected generator going this N of panel board.or maybe can we use nuetral from bus bar? why they are using this kind of power supply, nrmally power supply inout is l1l2l3, buth here added N & PE thanks again.
