Hi,
I have been given a homework question that im abit unsure where to start and how to go about it. Question below:
---------------------------------------------------------------------
Three houses are connected to a symmetrical three phase 400V, 50Hz supply, fed from the local LV substation distribution transformer. The transformer is a three-phase, 4 wire, unbalanced star, with the out of balance current flowing down the neutral as normal. The houses have loads with the following resistances:
Brown Phase house load = 20Ω
Black phase house load = 15Ω
Grey phase house load = 10Ω
If a fault occurs so that the neutral breaks at the transformer, calculate the individual house voltages.
----------------------------------------------------------------------
Any help or direction would be much appreciated!
Thanks
