We are generating the power by generator in Three phase
system. These three phases can be connected in star or
delta connection. In case of stare connection there is a
neutral point of three phases. In normal condition the
voltage and current flow from neutral is zero. But in the
case of short circuit or during any fault there is flow of
current and voltage in neutral. Generally the neutral is
mostly used for protection purpose and in the case of
single phase and neutral connection, the neutral is used
for return path.
