We in my plant one of the transformer showing neutral to
earth voltage is 22V how to solve it

Answer Posted / k.prakashchandra

Disconnect earth and measure voltages between phases and
neutral on some load.If the voltages are not equal there is
a loose connection in the star point.Before doing
this ,check the earth connection at neutral bushing.
