1.Whats the use of GNAC(Generator Neutral Accessory
Compartment)
2. why generator or any other system require Neutral
Grounding and not Phase grounding
3. what happens if any one of the phase is grounded.
4. if 15kv is grounded directly what will happen, why it
should not be grounded like that
5. use of of NGTR(Neutral Grounding Transformer and
Resistor) for grounding is helpfull and how

1.Whats the use of GNAC(Generator Neutral Accessory
Compartment)
Mounting of neutral side CTs and connection to NGR/NGT
2. why generator or any other system require Neutral
Grounding and not Phase grounding
If you ground a phase, you get a soild line to ground fault
3. what happens if any one of the phase is grounded.
An earth fault
4. if 15kv is grounded directly what will happen, why it
should not be grounded like that
Fault current will flow limited only by the impedance in
the circuit
5. use of of NGTR(Neutral Grounding Transformer and
Resistor) for grounding is helpfull and how
They both limit the earth fault current
