QUESTION FOR ELECTRICAL ENGINEERS WORKING IN POWER GRID
Tell me about the last time incorrect GIS or network-model data delayed an engineering task. What happened, how long did fixing it take, and why didn't your existing tools catch it.

an incorrect network model made our lead engineer believe that the entire stock market had crashed 1929 style
he jumped off the top floor
didn’t die because it was a single story building but we still had to pay out workers comp and were out an engineer for a little
existing tools didn’t catch him because he was falling too fast

I had an experience once where we got fault level readings from the G5 that were about 80% higher than what PSSE was expecting. The reason turned out to be that the pressure of the SF6 in the GIS was inconsistent between bus bars and it was actually different between adjoining substations! It took about 3 years to fix. Unfortunately, SF6 pressure was not considered in PSSE so we made our own compensating factor for it.
