In a 3 phase,400v,4 wire system, 2 incandescent lamps, one
having 230v,100w and the other 230v,200w are connected between
r phase- neutral and y phase-neutral respectively. If neutral
wire breaks which lamp will fuse first and why?
Answer Posted / harsh
It might be .... the Phase issue ...
Phase R is Generally 120 angle ahead of phase Y...
Lets suppose A complax situation here..
We are now going to add an another Load of 300w in phase B
With same voltage drop..
At that time also 100 watt bulb would b fuse First...
