Answer / gunasekaran

for neutral earthing
1.for three four wire sys.
2.if it source end it should be earthed because earth fault
current getting return path.
3.resonance is avoided.
4.for distribution load to maintain the balance condition.
5.at earth fault condition ifit is solidly grounded voltage
buidup at another two phase are getting only 80%line voltage
so no insulation problem.
for body earthing
1. to avoid the shock.
