The only thing I would add is, there are better and worse electrolytic capacitors. Some good ones are rated for higher temperature and longer hours. Also, even the worse ones will last longer if they're not subjected to a lot of heat.
The vendor may have an interest in NOT providing the best...
I'm wondering if anyone has specifications on the average street light of 25 years ago, vs. today (for towns that are still using HPS lights - I know LEDs are totally different and usually much brighter).
I'm trying hard to keep all this relevant to my question. Basically, I moved to a town in...
This almost sounds like a question from someone who's PE license is not legitimate.
I mean, if you're a real PE, then you went to a lot of effort to get that license, and you should already know the responsibilities that go along with it. Putting your stamp on things is your assurance that...
A few weeks ago, I asked for information on anything that could be used to monitor power flow, and installed as a self-contained system, mounted on a pole, out on a power line anywhere instead of located at a substation.
Since then I have found links to several items that look like they could...
Thanks for the tip about the S&C circuit switcher. I was able to use that as a starting point for better directed search terms, and I found these, which are closer to what I am looking for:

I thought I posted this question last night, but I guess I hit the wrong button or something.
A couple of months ago, I visited a web page from a small company that makes these things, they're like a crossarm that you would mount on a pole with a 3-phase power line, but each insulator has a...
ccjersey,
I'm pretty sure your original post was mostly correct; it just had a few slip-ups. Bill took issue with what you said about numbers of conductors, but you were totally correct that a service with only two conductors will always be only a single-phase service, even if it is derived...
For basic theory on this stuff, I recommend the book "Boscsh Fuel Injection and Engine Management." I see it is available for $30 on Amazon. I don't know, it may be cheaper through a catalog such as J.C. Whitney.
The sections on pulsed injection are probably just what you need. The basic...
I've been working on a similar problem for a year or so, on and off. Sometimes I forget about it for a few months, but then I start wondering again, just what is a cost-effective and reliable way to do this? I have a latching relay which unfortunately only operates from 9V positive, three...
What are these European sidemarkers? Are they the ones right in front of the front door that have been on Subarus for a number of years and are now starting to appear on other models? I'm sure you could add them if you wanted to.
