Generator is normally feeds power to the infinte grid which
is having a number of generators connected.
If by some reson turbine gets tripped but if GCB not get
opened in that case there will be a reverse flow of power
from grid to stator wdg and the generator will behave as a
induction motor. In this case there will be a heating of
rotor end ring and and outer wedges of the same which will
in turn damage the rotor winding. To avoid this reverse
power flow is resricted by tripping the generator on
reverse power flow.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
