We will have a couple of high school (~16yr olds) interns this summer at our engineering firm. I am trying to find good intro to power engineering videos, talks, website that we could have them look at to help give them a feel for the industry. Some of the engineers will give them some talks on...
Looking for suggestions on what equipment people have used to monitor either SF6 or oxygen in the building that houses SF6 switchgear. Got a request from a client, but have not used monitoring outside of SF6 pressure alarms.
Thanks

This happened a while ago so may have already been discussed, but I could not find any thread. The IEEE had a story recently about several (17) transformers that were shot at in Silicon Valley CA. The story says that 17 transformers shot but no outage. I've been trying to figure out how that is...
I see posts every once and a while regarding training and education for power systems so I thought I'd post this. the Manufacturer ABB has several upcoming webinars on protective relaying topics. Here is a link to the details page.

I do not have any affiliation with ABB and...
I was recently talking with a municipal electric Dept in the Northeast US about some percular faults on thier distribution system during 1 of our many snow storms this year. They had several (3+) different instances where fuse cutouts appears to have flashed over from the tops of one to another...
Does anyone have a form for logging relay targets at a substation? I am thinking of a sheet or card that would be placed near the relay panels that the substation operator can fill out to record any targets/messages before resetting them. I know newer electronic relays will also log this data...
Hello All,
I am looking into equipment that can be used on a distribution system for tracing or determining the phases throughout the system. This information would be more for system maps & load studies & not circuit interconnection.
I have found a few systems online, but am wondering if...
We recently had an operation that caused 2 primary (2.4kV L-N) PT fuses to blow & are thinking it could be caused by Ferroresonace, but wanted to see if anyone has had similar experience.
A relay mis-operation (no fault) caused several CB to trip that left 2 cap banks (1200kVAR each) connected...
Is anyone else using the white LED bulbs in GE ET-16 indicating light sockets w/external resistors.
We have specified many of these with white, red, green & amber LED bulbs depending on application. We are seeming many of the white lights getting dim over 2+ years while the other colors are...
Could someone explain the difference between a Trip/Close control & a Raise/Lower in a RTU? This came up in a GE RTU, but believe most RTUs have these different control types.
I understand you would use a T/C for circuit breaker or other device you want to open & close & that the R/L would be...
I am trying to plot ANSI C (17x22) dwgs to a Xerox 8830 and am finding that even when I use the center plot function in ACAD and the preview looks correct, that the plot will have slightly different margains left-right, top-bottom. Plotting the same dwg on our HP plotters it is perfectly...
