Answer Posted / arif pathan
There are many reason for using Low voltage(415V,3ph)in
Houses:
1) Due to use of 415v at LV side of tranformer the Fualt
level & short cicuit current will be less compare to HV
side , hence you will require small size of cables upto
your main distribution panel.
2) If your short circuit(kA)& fault Level(kVA/MVA)is less
you reqire small rating of CB or SFU for protection.
3) Due to 415V (L-L) your operating devices, equipment can
run on 230V (P-L) For which they are designed.
