Current flow

I was in control of a 4H's camp in NC, that fricken' horse fence would NAIL you. They ran the cloth ribbon cable like the video. I don't have a whole lot of respect for someone willing to test it barefoot. To each their own. Don't knack the safety aspect with harsher outcomes. I have a hospital pic of a phallus after urinating on a 600V tranny. Talk about cringe

Let's be more respectful to people asking safety questions, legit, or not!

I recently read a story about a guy found lying below a hi-V transmission line with his crotch still smoking. He apparently was perched atop the tower and decided to relieve himself.

Well that'll learn ya'.:roll:

There are several current sensors on the market, but I have yet to figure out they work.

Check out the Hall Effect. They make current sensors and electronic compasses from Hall effect sensors, and a whole host of other neat gizmos.

If you do search on the web for Understanding Capacitive Voltage Sensors you should find the information that you are looking for.

I prefer to believe it is measurement by black magic. Knowing how it works would spoil the fun

volt stick/ glow stick, whatever you want to call them are about as usless as a football bat..... sometimes they glow when they should, sometimes they glow when they shouldnt, they flicker when you bump them, and they are sensitive to static electricity....... I dont trust them, I could flip a coin and trust the outcome of whether there is voltage present just the same, I use a meter...

I use a meter...

A high-impedance voltmeter or a low-impedance tester such as a solenoid-type?

Might be able to check electrical heating elements for opens.

...

If I remember my basic facts correctly, when I have an open, no current will flow in any part of the circuit. Use the nc voltage sensor for this purpose, opens, and the current probe for current flow on grounded conductors.

I have an assorment of meters, I like a digital for checking voltage on circuits im just checking to see if they are live because its easy to read, but for troubleshooting, I prefer an analog meter, digitals read too much noise and give ghost readings, and I break out the wiggy troubleshooting also...
