Answer / sheikh

i think voltage b/w earth and neutral should be zeero.

Answer / hemant

voltage btwen earth and nuetra must be zero, then and then
only its give close path to nutral for single phase or 3
phase 4 wire system if not then its difficult to drive
equipment on such circuit.

Answer / harikesh yadav

voltage and earth resistance 0 to 3 volt acceptable in india

Answer / koti

voltage should be less than 5 volts (to avoid mal-functioning of controls) and resistance should be below 50 milli ohms.

Answer / pradyumna chandra panda

the resistance b/w earth and neutral 1.8 kohm is accepted and in 3phase supply voltage b/w earth and neutral 3v to 20v is accepted.

Answer / jayasen jena

the voltage mot be less then 3 & resistance 100 milli ohoms

what is the resultant phase shift in a 3 phase power system including neutral if on or more phases gets grounded or short circuited. kindly explain in detail for the reasons...
