Hipot results vs surface area
I trying to hipot test a 12"x12" metal with kapton layer. Different sizes of metal (e.g. 1"x1", 4"x4", banana plug) is placed on top of kapton tape. The bigger metal ...

Trying to make a HASEL actuator
I was told that if I apply high voltage to a zip lock bag filled with baby oil with tin foil paper on the end it'd make it contract and act as a HASEL actuator.
I'm afraid of measuring the exact ...

DC hipot leakage current
I noticed that when testing hipot in DC I always get leakage current, but not during AC hipot testing. Do you have any ideas about this? My hipot tester is Quadtech Sentry 500VA. I’m testing a ...

What material can I use as a dielectric in my own high voltage capacitors?
I need capacitors rated for 50 kV. Buying them is an option but the ones with appropriate voltage rating I have seen cost more than 50€ which is far too much.
That's why I want to make caps on my own ...

How come distilled water hasn't replaced transformer oil as a high voltage insulator?
I've noticed that distilled water has an extremely high dielectric straight (65-70 MV/m).
With that considered, how come it isn't used in the place of transformer oil for 10-20 kV applications where ...

High voltage dielectric breakdown & layering insulators
I’m going to use 230 kV as the reference voltage for the example below;
I know if I put a piece of metal too close to a 230 kV source it will breakdown the air and jump to the piece of metal causing a ...

What is the correlation between dielectric plates and capacitance? [closed]
A project I'm working on requires a capacitor of 37000 uF and a voltage rating of at least 10kV, but every capacitor I find online can only meet one of these standards and is very expensive, so ...
