Hello everybody,
I have to adjust the relay settings in a ungrounded system at 13,2 kV, and I want to know if there is a stardard setting for 3V0 (using broken delta for the measurement) in the detection of ground faults. I think an adjustment at 0,1*Vnominal must be right considering that: in...
Hi everyone,
In a industrial voltage level, I want to know how the fault current magnitude changes when it passes through a 12-pulse converter.
Thanks!
In the IEEE 1584 through the fault current we calculate the Iarc and Iarc reduced, and then the incident energy. But, in the NFPA 70E, I didn't see anything like Iarc reduced, just fault current. This concept is only in the IEEE 1584? The table 130.7(C)(15)(a) in the NFPA make some generic...
