Creating 1Tera-Ohm divider at 100kV

Creating high voltage components is challenging because of the parasitic capacitances to the surroundings. The electrical field at 10KV requires careful isolation of any conducting surface of about 1”; furthermore, any sharp niches can trigger an arc between the component and the surrounding lower potential items. Goal I needed to measure high voltages around 30KV; …

My new gig: Static electricity measurements

Understanding and measuring static electricity has been of an interest since I was a kid. Finally now, I can spend the time to play with this new-old hobby. Let me start with video clip showing the instrument in operation: Demonstration of the Coulomb meter prototype Now, let’s see each building block of the Coulomb meter. …
