Why the resistance grounding (NGR) is better than Solid grounding?..

Answer / sourabh

Grounding resistors or
reactors are often used in medium voltage systems. These
current limiting devices are connected in series with the
transformer secondary neutral. In the event of a phase-to-
ground fault, the current will flow through, and be limited
by, the neutral resistor or reactor.If a phase-to-ground
fault occurs on any phase cable it will cause fault current
to flow back through
the earth, from the earth into the remote ground, then back
through the grounding resistor to the transformer
neutral.
