what is the difference between earthed and unearthed cable?

Answer Posted / rakhi kawatra

Earthed System : the neutal point or mid point connection
is earthed in such manner that even under fault conditions
he max. voltage that can occur between any conductor and
earth does not exceed80% of the nominal system voltage

Unearthed System : an electrical system which does not
fulfil the requirement of the earthed system.
