jmmendicoa Posted December 10, 2006 Report Share Posted December 10, 2006 Hi ,does anybody knows a project for building a High Voltage Probe from 0 to 30 Kv .I will apreciate if send the project to me Quote Link to comment Share on other sites More sharing options...
LiveRock Posted December 12, 2006 Report Share Posted December 12, 2006 if you are thinking of measuring high voltage, you can check below:http://dawntreader.net/hvgroup/divider.html Quote Link to comment Share on other sites More sharing options...

steven Posted March 30, 2007 Report Share Posted March 30, 2007 :)i posted a high voltage probe circiut schematic in the high voltage stuff section somewhere agers ago it should still be there look at topic high voltage circiuts if it hasent been wiped by hackers it should still be there , if not go to the site tesla down under thats where it comes Quote Link to comment Share on other sites More sharing options...
Freddybaby Posted April 26, 2007 Report Share Posted April 26, 2007 Is your application for just DC or do you need compensation for HF (Like a scaled up scope probe) ? Also, the load resistance of your meter/s must be consistant as this will affect the ratio. Simple DC method30 1M, 1000V rated resistors ( or whatever you can find for 30KV)To determine the low voltage resistor (R2)R1 (30M) / Ratio-1 (Lets say 1000/1 ratio)30M/999 = 30,030.03 (This is the effective tap resistance)Then determine the parallel resistance across your load (meter) to get the proper ratio.(10M * 30,030.03 ) / (10M - 30030.03) = 30,120.48 ohmsThere are other factors to consider such as temperature and voltage coeffecient andpossible corona discharge at above 15KV. This can be reduced with large conductorsizes and potting (difficult to do correctly).Good luck Quote Link to comment Share on other sites More sharing options...
