Reduce 5kV DC 100x - Is it Possible?

In summary, there is a circuit called a voltage divider that can reduce voltage by 100x. It is also known as an EHT probe and can be purchased commercially or made using instructions found online. However, it may be safer to purchase a high voltage probe for your multimeter instead of attempting to make your own.

Is there any circuit which can reduce voltage hundred times (100x), i got 5kV DC and my plan is to low that 100x and measure with multimeter. Is that possible?

Yes, there is. It is called a voltage divider and uses resistors in series to reduce the voltage.
Used like this, it is sometimes called an EHT probe.

You can probably buy them commercially and this may be worth checking.

Constructing one that could be used safely may be difficult.

However, there are articles on Google that suggest you could make your own.

I will look for this on web
thx 4 clue

Don't try to make your own. Merely choosing the right nominal ratio of resistors is not good enough.

I agree with sophie -- it's much safer to just get a high voltage probe for your DVM. This one is from Fluke, but you can also find others:

FAQ: Reduce 5kV DC 100x - Is it Possible?

Can 5kV DC be reduced by 100 times?

Yes, it is possible to reduce 5kV DC by 100 times. This can be achieved through the use of transformers, which can step down the voltage to the desired level.

What is the purpose of reducing 5kV DC by 100 times?

The purpose of reducing 5kV DC by 100 times is to lower the voltage to a safer and more manageable level for various applications, such as in electronic circuits or power distribution systems.

Is it safe to reduce 5kV DC by 100 times?

Yes, as long as proper safety precautions are taken and the reduction is done correctly, it is safe to reduce 5kV DC by 100 times. However, it is important to consult with a professional before attempting to reduce high voltage levels.

What are the potential risks of reducing 5kV DC by 100 times?

The potential risks of reducing 5kV DC by 100 times include electrical shocks, short circuits, and damage to equipment. It is important to follow safety procedures and use proper equipment when handling high voltages.

Can any type of transformer be used to reduce 5kV DC by 100 times?

No, not all transformers are capable of reducing high voltages by 100 times. Specialized transformers, such as step-down transformers, are designed specifically for this purpose. It is important to select the right type of transformer for the voltage reduction needed.
