Answer / kumar

therotically it should be 0V. But practically differences
lies for which upper limitis are been mentioned.
For electronic systems like telecommunication it less than
5 V, for power systems less than 100V.

Secondaly , it may connected to earth depends on what
neutral you system needs i.e. fixed or floating.
Moslty it is connected to earth for safety of personal &
euipment.

Answer / jais thomas

THE EFFECTIVE VOLTAGE BETWEEN THE N AND E OF A SYSTEM
SHOULD BE ZERO WHICH MEANS THERE IS NO SHORTING,
DEFINITELY THERE WILL BE CONTINUITY BETWEEN N AND E BECAUSE
THE N THAT IS GENERATED IN A STAR SYSTEM TRANSFORMER IS
GROUNDED WHICH MEANS THAT THERE IS A CONTINUITY IN N AND
E.THIS SHORTING BETWEEN N AND E SHOULD ONLY BE IN THE
TRANSFORMER LEVEL AND NOT IN ANY OTHER PART OF THE SYSTEM

Answer / abdul salam

The exact voltage between earth and neutral can not be
forecast because it ia not a fixed quantity it depends upon
the how effective neutral earthing is provided to the
system and howmuch unbalancing of load is present in the
system, ideally it should be zero but can not be achieved
as some unbalancing is always there in the system.

There should not be any continuity between earth & neutral.
