Answer / deb

-Neutral-earth-0 volts(max. 5 volt)
-if Neutral-earth-1 volts, means perfect earthing(in a
office where load present.
At this condition neutral-phase voltage will bw higher than
earth-phase voltage. because leakage current pass through
neutral.

Normally neutral-phase voltage-220 +-10 and earth-phase
voltage same at no load condition(earthing 0 volt)

means if earthing in a office where equipment is running
and earthing voltage suppose 2 volt . the neutral-phase
voltage should be suppose to 220 volt and Earth-phase
voltage 218(neutral to phase voltage 220 volt-earth to
neutral voltage 2 volt = 218 volt).

Please currect me if i wrong

Answer / samdipth

i think the difference will be between 1 to 3 volts.....and
the answer no 9 please let me know how come the equipments
will get damage if the difference will be above 3 volts?

Answer / gopinath

Pahse to Neutral 230vac
Neutral to erarthing 0 to max 3vac
Earthing to phase 230vac

Answer / devendra kumar

440 volt three phase system
line to line 398.36 volt
phase to neutral voltage 230 volt
phase to earth voltage 230 volt
earth to neutral voltage 0 volt in single earthing without joints
and with joints Neutral-Earth= 0 to 5 volts

Answer / chandrakant rewatkar

min voltage is Zero ( if no joints)
max voltage is 3 volt ( if there is the joints)
if these value get in case of 3phase supply with P and N
if supply voltage is 415 without variation in voltage.
if value is more than 3 volts,
then load is unbalanced
Earthing not perfect
neutral not proper from incoming supply

Answer / shailesh singh

the voltagr between neutral and earth should lies between 0
to 5 vlts depending upon earthing arrangement.

Answer / ambalavanan

2 volt

Answer / prasad das

The voltage differance between neutral and earth
will be zero,if it is perfectly earthed.

5 Answers   Power Grid,

Just a silly question but just to make my curious mind bac to normal - Why was not 67 and 67N relays built into a single relay as i have noticed that the R,Y,B CT wiring end up into the 67 relay while the common of the R,Y,B CT wiring end up into the 67N relay. Then it was better if a single relay was manufactured just like the distance relay (21). Another question i would like to ask is - how do we know where the 67 and 67 N relay has to be placed.why is it not placed at the transformer bay? In the substaion that i am working -i have noticed that it is placed between a breaker and a common double bus bar and this line bay is connected to another substation at a remote place which is furthur connected to a load. B U S______CT for 67 & 67N ______Breaker _____ remot s/s. B A R
