Answer / m.gopinath

It will be better explained with a example:

The Geyser will have three terminals viz phase, neutrl and
earth. The phase and neutral are given to the Geyser coil
for heating and earth connected to Geyset body to avoid
body shock. If the earth and neutral are connected
together, the current will flow in the body not in the
geyser coil. Hence the geyser coil can not heated up.

Answer / vijendra joglekar

We can short both earth and neutral notihng will hapen but
in case of any fault in the equipment the fault current will
flow directly to the earth .So as per the IEEE standard that
is not correct way to do the electrical coneection.

Answer / kiran@c&selctric ltd

supporting that answer it also causes shock to human beings
when we toch the body

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.

we done magnetic balance test for 33KV /440V transformer in our company , but the ratio out is confusing us Voltage applied in RY = 440 , at RB = 320 and YB = 60 RY 440 = ( RB + YB ) 380 only Please let me know what type of problem is it.
