Villard cascade on mains voltage



It is operated with 50 Hz. Mains voltage so. Prior to the test with 24V.

That I need 100µ up testing jobs I doubt Very much heavily. The Threadersteller 15nF had used even in the other thread (Villard cascade (high voltage cascade)) and it ran...
I want to not know ...und for bucket I got at 1000V and 470µ...

anywhere else that must chop sit... If the other has also gefunzt...

and the circuit looks the same. Is the same as listed in the annex.


With a 22nF capacitor you have an internal resistance of 150Kohm that makes per level after 3 levels already 450Kohm if your instrument has an impedance of 1Mohm, you measure then it only 2/3 the voltage

OK, apart from them, why always remains the same voltage because? And if something would change, but it's just my meter, why can I do then no funken-(strecke) at 230V?

Test way back touched at 24V input and more than A little bit krisseln Institute also does not...

Was measured with a Power System Studies commercially available fluke 192 and once with a fluke of Scopometers 196C...

And how can getting rid of the problem?
I'll buy me an extra gauge never just for such a stupid circuit...

Registration questionnaire.



This also a question Completions Specialists would fit that prevents exactly the people ask stun. Anyone who has a little experience is pure left with electronics, but those who don't even know in which direction the technical stream flows, which should remain outside and try again later.

A schematic with a voltage divider and a MOSFET is very good to keep out unwanted guests: any questions:
What happens when it gets warmer?
-The load on the relay is switched on *.
-The load on the relay is switched off

The NTC is the fixed resistor eine(n)...?
-Bridge circuit
-Voltage divider *.
RC element

Which component would be suitable for the MOSFET schematic (Google)?
-1N4007
-IRF9530

Times suggestions for easier questions:

Is the voltage measured in what unit?
-Antwort1
-Antwort2
-Volt (V) *.

Is the current measured in what unit?
-Antwort1
-Antwort2
Nanoamps (A) *.

Berechtnet the electrical power is out?
-Antwort1
-Antwort2
-Voltage and current (P = U * I)

Can answer anyone who is motivated to learn about electronics, dan.

I think this is somehow too 'difficult'

When I came to the Forum, I did not know what is a mosfet, or how to calculate a resistance...

Hobbyists meeting 2014 - Planner/Organizer looking for



lately questions are always high voltage cable jointing loud, whether there be a hobbyist meeting 2014 again
I would also look at such an event and here once live treat yourself to the unique Club me: mrgreen:

("Organize myself what!", some think now.
Legitimate objection, I'd like to, but first, I have this year hang the matura, which will keep me still neatly on their toes (and does it, in part, already), by the way, I have some projects that are very important to me, but strongly be taken thanks to high school in the length. I got time from 10 July again. Above all I live but in Italy, and a few of you would find it to travel in the distant South Tyrol to come to a meeting.
Logistically, central Germany was again ideal (and me of course the South dear would be).)

So now my question: does anyone have the time and inclination, the Orgnisation of hobbyists meeting 2014 to übernehemen?
I hope that we find someone!
So it is but probably a lot of work, who acquires the Organization, should not be from the outset is clear, that he (the I can save it to me here, or? ^ ^) will invest much effort - does not have, that an interim meeting left because someone jumps down!

Even a short request on my part if it is what: Please after July 10, because I got up then my Matura exams!

I like making the proposal. I can't get to organize your complete but unfortunately also. But I me offer, those taking it in the hand where I can support.So when the structure, the get from Bierganituren or whatever it takes.

good that you made a start now, I hope someone has a good location.
Should it be away not too far, I offer me like to help at the on - up and removal. Unfortunately I can provide no location, but perhaps someone can overcome is that anzufreifen.
However, should one be aware of security risks and define clear rules with regard to that.
Nothing more despite: I gladly offer my active help.If my itinerary is below 400 km and it takes place on a weekend I'm in also. Organizationally I could offer for a Web site or general help "Media presence".
