    Under-Voltage Load Shedding in the US

    Hi, I'm currently do some searching on the UVLS practice in the US and have some difficulty in confirming which states actually in the Eastern Interconnection actually follow this practice. NERC came out strong with this by setting up UVLS working group back in 2006, but did not see any report...

    IEEE 605-1998 and Bus Bar Short-Circuit current withstand capability

    Desertfox, The reason why i was looking for the short-circuit withstand capability is that we have one of the buses in our system which comes pretty close to the designed electrical current rating, and I was not certain if the same rating is adequate given the present configuration. Through...

    IEEE 605-1998 and Bus Bar Short-Circuit current withstand capability

    Thanks desertfox, I have seen that document in the past, but not quite sure how did they come up with the .866 or .808 factors. Also, how can these factors be applied to calculate, electrically, the maximum fault current that the bus should be able to withstand. If I were to obtain the...

    IEEE 605-1998 and Bus Bar Short-Circuit current withstand capability

    Hi All, I'm a bit puzzling by the Gamma Factor of 1, .866, and .808 listed on Table 2 of the IEEE standard as adjustment factors for the bus force depend on the type of fault and conductor location. I'm seeking advice on: 1) If you have any reference or document showing how these factors were...
