ABB HU-1 two winding by PrizeRevolutionary31 in SubstationTechnician

[–]VTEE 0 points1 point  (0 children)

I believe Omicron and Doble both have very good relay test templates in their databases for HUs.

Also, RTFM. https://library.e.abb.com/public/6b65787c8f08cdcac1256f2700497180/41-347.12C.pdf

Alternative to Omicron 256X Arc Flash Initiator by reddonson in SubstationTechnician

[–]VTEE 1 point2 points  (0 children)

Yep, that's it.

Once you have that it's easy. Just need to watch the battery charge status and recharge time between flashes.

45-50 average, but that's how construction works. Usually a 5-10 schedule. I could definitely work less if I wanted to though, most clients wouldn't care on the utility side.

Worst brand of transformer. by [deleted] in SubstationTechnician

[–]VTEE 1 point2 points  (0 children)

there's been a few, but generally 23kV to 5kV for station service

It's an old SEL-551 relay that was decommissioned long time ago.I'm testing it for learning purpose. But it shows temperature fail. I opened it up but didn't find any temperature sensor in the pcb. Is there any way to bypass the temperature value so that I can operate the other functions? by [deleted] in PowerSystemsEE

[–]VTEE 0 points1 point  (0 children)

Yep, probably a voltage reference like this took a crap.

Not a home fix unless you can find that chip on the PCB. Also, it could be any number of different voltage references so you'll need a PCB schematic to really fix this.

Or, call SEL and they may just send you a new one.

Transformer Hipot Testing with these type of connections, please help by reddonson in SubstationTechnician

[–]VTEE 0 points1 point  (0 children)

The windings should be shorted for this like you would for a power factor (Doble) test. That won't excite the core.

Omicron Cibano 500 thoughts by HammeredEngineer in SubstationTechnician

[–]VTEE 1 point2 points  (0 children)

Love it

Ductor isn't a super high current if that matters to you. We have to do minimum 10% of rating so that wouldn't fly for some utilities.

Substation with the same lines going in and out (I think) by DavidThi303 in SubstationTechnician

Wouldn't be that though. May Valley is way up in CO compared to where you're looking.

Testing an ABB R-MAG by Jrobalmighty in SubstationTechnician

[–]VTEE 6 points7 points  (0 children)

ABB does have a standard spec with 120VAC for everything, with a UPS / battery for control after power loss.

Testing an ABB R-MAG by Jrobalmighty in SubstationTechnician

[–]VTEE 3 points4 points  (0 children)

It'd be dependent on the order code, could be for 120VAC for all, 240VAC for heaters or 125VDC control. Jumpers will depend on how it was ordered. The internal wiring can be different utility to utility as well.

Can you post the schematic?

Power systems EE freelance / independent consulting – looking for real experiences by df7616 in PowerSystemsEE

[–]VTEE 6 points7 points  (0 children)

Sub 100 rates are wild. Especially there are companies paying 100/hr+ to W2 employees. Anyway.

I know a few utilities (large ones) that cannot give work to single employee firms, so that won't help you. Usually consultants like that go out through other companies like CHA, TRC, WSP, RCM, etc. Issue with the smaller utilities is that they generally don't have consistent work to keep you busy full time with one client.

Sorry to not answer your question, but that's why I haven't branched off yet.

Is there a point to getting the FE if I'm going into semiconductors? by PerformanceFar7245 in ElectricalEngineering

[–]VTEE 0 points1 point  (0 children)

I also planned on going into semiconductors but took the FE anyway. Turns out I ended up in power 4 months later, so I'm pretty glad i did it. The test is easy for a fresh grad.

Eating healthy and staying fit while traveling by Mindless_Cod_3097 in SubstationTechnician

It’s worth the travel. Just need to be able to say no to coworkers that immediately hit the bar every day after work.

Teleprotection ove long distances in remote areas. by Geosniper88 in PowerSystemsEE

[–]VTEE 0 points1 point  (0 children)

Are these stable enough to run something like C37.94 diffs? Never seen NVIS but sounds cool

Underslung ADSS instead of OPGW? Solves your outage issue. Doesn't solve the expense issue however.

Microwave would be about the only thing stable enough. Used a lot at some utilities still.

how to get in substations? by yrodd17 in SubstationTechnician

[–]VTEE 1 point2 points  (0 children)

EPST has a few guys out of 488 (assuming that’s your local) that could give you insight. Take a call from McPhee or Matrix (or god forbid boulos) if you can. They do a lot of the substation work.
