It's definitely on the list!

Also is that Nolan Partridge??

Lol it is.

@@testingtechtips Great guy! That’s good company in a creepy long tunnel lol!!!😂

I'm assuming most, if not all the relays you want to fire up take 125VDC. There are a couple ways to make a DIY power supply that can handle that but they're all varying levels of sketchy. Maybe I'll make a video about that someday, but for your use case I'd recommend just getting a 120V DC bench power supply. Last I checked there were a few on Amazon for $80.

@@testingtechtips Sweet thanks man.

Lol I assure you I was not 😅

I'm happy to help! I love doing this.

@@testingtechtips THAT IS AWESOME!!! I really appreciate you at the moment!! 👍

Fortunately the give you a sheet with the formulas during your exam. It's just up to you to know how to apply and solve them.

Like TTT said you have access to a formula sheet and you can download a copy at the NETA exam website to review. It doesn't have everything though (for example available SC current), my advice is to practice using them and get an understanding of what the formula is "doing" rather than just trying to hammer them all into your skull through wrote memorization. As a simple example instead of trying to memorize that I = E/R, remember that your current should be higher as voltage goes up and lower as resistance increases. Probably not needed for that example but for more complex formulas that sort of thing can help you remember what should be included and where and help jog your memory if you start getting confused. That approach also helps on questions where you're not asked to calculate anything directly but are asked "what happens when ... is increased in a circuit" Good luck.

Dang, I had two other mistakes that I caught in editing lol great catch. Thanks

Thanks! Yeah RUclips videos aren't a complete replacement for classroom learning but I like to think I can help a little bit.

Trigonometry is the basis for most math a NETA tech requires.

It doesn't feel dangerous when we're doing it! We take a lot of time and effort to make sure we're equipped to do everything comfortably and safely - and to make sure we don't cause more switches to blow up haha.

Nice video quality! What did you use for the video?

Why mess with it if it works, right?

I found the Omicron software a bit limiting for what I wanted but I never actually got training on it so I'm sure I was missing something haha.

@@testingtechtips try the new Omicron CMC500! That is "the real Device"!

I have a few hours with it under my belt but not a ton. I've always used an F6150 and protections suite, and never had a compelling reason to use anything else. I know it's solid hardware and all the guys I know who use the CMC have a similar love/hate relationship with the software. Maybe I'll play with it more at some point and report back.

@@testingtechtips I find the omicron does so much for you it turns you into a push button tester.

Oh my god yes! It's terrible. Though I think I forgot to mention that was my favorite benefit over the 6150 was that you can program how loud the beeper is.

Agreed. The 6150 is such a good test set, I'm not sure what the push was to abandon it for F8.

Couldn't agree more.

Yup. It's going well so far, compared to my last few gigs!

@@testingtechtipsthat’s where I work too, great company.

Good to hear, I love working for Shermco. Well rounded teams all around. Glad to have you aboard.

Thanks! Glad you found it helpful.

Sorry, nothing on the 889 yet. I make about one video a month so it'll take a while to work my way down the list.

Of course! Thanks for the support.

My biggest complaint with most "training" classes has always been that they're too vague, and you can't take what you learned and immediately use it in the field. One thing I focus on is lasering in on one topic with real examples, start to finish just like I'd train guys in the field. Thanks and good luck on your test!

I've seen the Powermetrix units used for in-service checks. I'm assuming they work almost exactly the same way.

@testingtechtips They can do both in service and they have a waveform generator. They spit out a nice looking report as well. The software runs windows xp and is kind of janky but after it's all set up it's really convenient. Powermetrix Powermaster 7 series

I'll check it out! Thanks!

Are you talking about the disclaimer at the beginning of my videos?

Hey thanks! I appreciate the support!

Happy to help, and thanks for the support!

Happy to help!

There is definitely some math. If you have the fundamentals of algebra down and can solve power equations (ohms law), parallel/series resistors and capacitors, then you should have enough to pass the exam.

Thanks, happy to help and good luck!

My videos are more tailored to the technicians doing the work in the field. Generating settings is definitely more of an engineering activity, but I'll have some videos covering a little of that scope as it relates to testing relays coming soon!

I probably wont be making any RTS videos, for a few reasons. #1 I'm a protections suite guy. #2 the whole point of RTS is that it does all of the work for you and you're just a pushing buttons. In my relay testing series, I'll do my best to explain the concepts and help you understand the math behind what we're doing when we test relays. Hopefully that'll make the steps RTS runs make more sense. If you need immediate help with RTS they have some very good paid training classes.

Haha thanks, I mostly use it as a caveat in case I get the facts wrong. (The comment section is always smarter than I am!)

Man I'm sorry but I don't have anywhere near enough detail on your specific application to help you with that one.

You're welcome! Thanks for watching

For most modern relays, if you are only downloading the settings from the relay to your computer, it should be fine. I would suggest against it if the motor powers something critical, but for most cases yes. You would want to take the relay out of service to install new settings as they may occasionally trigger outputs when new settings are loaded in. That said, you're doing it at your own risk so get a thumbs up from whoever runs the site.

I appreciate that and I'm glad to help!

It depends how you're testing it and if you've properly isolated the system upstream.

Awesome! Glad to have the support

I have to go off the few sources I've read including NFPA 70E D.3.1 which calls out the "industry accepted minimum" arcing current as 38% of bolted fault current. I preface that oversimplification by stating I'm not an engineer because it's absolutely not my area of expertise and is clearly not a key takeaway from this video.
