Answer / nilamani umashankar jena
when a fault occurs in domestic homes ,earthing is used to
provide a path for passing of fault current,it prevents
human being from electric shock.
but on the otherhand grounding is the phenomenon that
states that metallic part of every equipment is connected
to earth.this is called grounding.it is usd to prevent the
equipment from heating damage.

Answer / narendran
Earthing is done to protect the operator from any leakage / fault potential appearing on the body of the machine.
Where as Grounding of equipment are done mainly to prevent it from building static charges which other wise may lead to unsafe situations particularly when machine are connected to vessels handles explosive materials.

A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
