I agree with you respecting resistance will damp de transient. But how do you apply the ITI Curve to an oscillogram of the transient (either a measured or simulated transient).
All we know that most of the capacitor switching transients ( 1.0 to 2.0 pu peak) last between a few miliseconds to about 10 or 20 miliseconds, time for which the transients are almost damped completly. Then, according to the ITI (CBEMA) Curve, most of these transients are outside the "No...
AAK:
The generator is always running in paralel with the grid. It´s not used for backup.
You answered that the generator can be installed directly to the grid, but what about the stress imposed on the generator due to single line to ground short circuits ocurring on the 12 kV feeder?
DPC...
I work for a utility company where there are 12 kV feeders. The question is: Can a 12 kV, 4 MVA generator be connected directly to a 12 kV feeder? Is it necessary to install a 12/12 kV transformer to isolate the generator from the 12 kV electric grid? As aditional information, the feeders are...
