dear all:
please help me about testing leackage and capacity of high voltage (for example 390uf 450v)and i need schematic for this tester.

 

How small a leakage do you need to measure?

 

http://www.pa4tim.nl/?p=1385 good place to start

 

thank you very much.schematic of this paGE WORK GOOD?AND CAN I CHECK ALL HIGH VOLTAGE CAPACITOR?WHAT IS DEFORMER CAPACITOR?

It says REForming electrolytic capacitors.

That is when you apply a DC voltage to an old, leaking electrolytic with hopes that the DC current oxidizes the aluminum and cures the leakage.

 

thank you very much.please tell me the best way for testing electrolyte capacitors and if available send good schematic for building it.
