Gloves for electronic parts / high voltage parts?

Dear fellow people, 

Yesterday I tried to open up my ATX power supply and test everything if works, so I could transform it to a lab bench power supply. I knew that the two large 200v capacitors were dangerous to touch so I did my best not to touch them. But somewhere near the capacitors I touched gave me one hell of a shock that my eye view went to static view for a few seconds and I started to overheat and sweat, could not even talk normally. So.......... I want to buy some gloves I can use to handle these parts. I want gloves that fit well so I can handle parts easy, not like those thick rubber gloves. 

What gloves are good for these parts?

I also have these: https://www.safetysolutions.com/retail/item/080206898/51-151-EDMONT-GLOVE%2C-SZ%3A10%28LG%29/206898

But I do not know if they are good for handling like high voltages or even low voltages. They are made out of Vinyl. The tips of my fingers are not that good for holding smaller parts so I also need gloves that look like these:


I read these are good and not melting or conducting electricity. 


So my main question is if someone haves experience with such gloves and which one are good?

Turn the power off, and discharge the capacitors before you work on it.  A LOT of devices have interlocks that won't allow you to open the case with power applied.  There is a reason for that.  

ESD products won't help.  They are designed to conduct electricity, not prevent it conducting.  Capacitors can hold a charge for a LONG time.  If you don't know how to discharge them, google for it.

Here is the short, simplest way to discharge them.  I don't like even telling you this, because if you don't know what you are doing you can get hurt real bad.  The easiest way is to touch a screwdriver to BOTH terminals of the capacitor. It will likely spark.  BIG capacitors (not common in modern equipment) can actually weld the screwdriver to the terminals.  Hold it there for a second or two, remove it for about 5 seconds, then touch them again with the screwdriver.  Any capacitor bigger than a pencil eraser  should be done like this, WITHOUT TOUCHING ANY CIRCUITRY WITH YOUR BODY.  I also recommend using the old TV repairman trick of keeping one hand in your pocket when doing anything on a circuit that might have dangerous voltages.  If you do get shocked, that lessens the chances of the current going through your heart and stopping it.  It only takes about 10 to 20 milliamps through your heart to kill you.

Yes, I already saw that discharging method on the internet, but I also read that it can recharge itself even if the power is not connected to the capacitor, is that correct?

Before testing the discharge method I just wanted to be sure that that there could be an easier and safer way to do this.

Yes I read about what amps are lethal.

Till 0.1 amps has a sensational to painful feeling, from 0.1 till 0.2 is lethal, above 0.2 can do a lot of damage and burning, but there is a chance to revive and safe that person. Read it here http://www.physics.ohio-state.edu/~p616/safety/fatal_current.html


Certain types of capacitors "can" recharge spontaneously (I use that term rather than "recharge itself" because they don't recharge themselves.  They get a charge from the atmosphere.  The only type I know can do this is the capacitance inside and old (CRT) picture tube.  I don't think you are playing with those.  They get the charge from static in the air.  A lot of common (especially electrolytic, the kind you are dealing with) capacitors "appear" to recharge themselves after being drained.  But that isn't what is happening.  What happens is, the charge can't come out fast enough.  It basically gets trapped when trying to come out that quickly from the material.  After you disconnect, thinking it is discharged, the charges migrate to the terminals and it "appears" it has recharged itself.  That is why I said to repeat the process instead of doing it just once.

bdk6, glad you added that last part instead of leaving it the it mysteriously charges from the air. It is a problem with migration speed.

What I would suggest when working on potentially lethal voltages is, after turning the power off, hook a clip lead from the high voltage lead to ground, —and leave it there !


It seems he is bent on doing things his way, and finding any random web page to support him.  No matter how questionable the information.  I have 30+ years doing this stuff and a degree in physics and I STILL pay close attention to the big yellow warning labels.  You can lead a horse to water...

My question to you is, why do you feel the need to touch energized high voltage parts?  That is NOT the right way to do things, which is why you can't find gloves to do it with.  Instead, use a well insulated probe attached to whatever measuring device you need.  Your finger is NOT a measuring device, unless you consider death to be a valid indication of a live circuit.

I am pretty sure to modify something you need to touch it. I just don't want to risk any shocks anymore while doing something on something this dangerous. For example, I have a second ATX power supply I want to salvage everything from. Therfore I need to touch them to desolder and take apart. I don't want to die doing this. 

Will ESD products help? I mean on capacitors with high voltage rating?

Like ESD gloves and ESD wrist band? Or will I still get a shock if the voltage is high?


No, an ESD wriststrap, if anything, will make certain you are grounded, so the electricity has a path THROUGH you to ground.

You will only know it for an instant, because after that, you will not feel it.  You will be DEAD.

When working around high voltages NEVER ground yourself. It is a quick way to end it all.
