Ngr is using fault current reduced and flow to ground

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.

NGR: Neutral Grounding Resistance

NGR or grounding transformer using in MV voltage and Soild grounding is using in High & low voltage level as per standards.

Answer / revathi

In resistance grounding the phases connected to ground
through resistors. it resists the excess flow of current
and trip the circuit.
