Thank you gmax, My manager has been placing me in the upper two levels of the groupings for a lot of the software packages and skill sets. I think he’s correct according to the work independent and teach others requirement, but I feel like I’m more of a lower level just because I seem to...

What competency matrix are suggested for power consultant engineers? My work organization has a competency matrix of different skills. The skills included different software packages and engineering practices for low/medium/high voltage power design and instrument and controls. Some of the...

Thank you Scott and Russ. The company has a relaxed and positive environment and seems to be in between a small and big company in attitude. As far as work environment, willingness to support work/life style, I have no room to complain. The company encourages engineers to attend local...

As a titled engineer I’ve worked in manufacturing and electric utility. Now, I’m working for a consulting group. I’m wondering, is it normal for consultanting companies to be disorganized? Example, we don’t have general breakdowns for the type of work we do. It could be substation, switchyard...

Thank you unix101os, I was hoping someone might be familiar with ringing voltage or other examples of calculating possible problems. I spoke with some of the silvered hairs at work and they were able to tell me about the time when vfds become popular in their areas, and the problems they had...

Can someone point me to an understanding of why VFD rated cable include Inductance and Capacitance? For example, Belden cable 29504 shows impedance, inductance, capacitance between conductors, capacitance between conductor and sheild, and DC resistance. Is there a VFD motor calculation that is...

Thank you for the welcome sign and thank you very much for the two links. The diagram in part 1, showing the failure of the bathtub comparison to power flow would have helped many a student in school. and the mantra in part 2 has opened a KISS method for understanding the relationship of power...

Can someone explain how the power flows out of the house in terms of voltage, current and waves? Say the service voltage is 242V AC as measured from where the utility is connected to the house. Does the grid-tie inverter react to that and put out 243V AC, in phase, so that the net power flow...
