I am planning to buy a Tesla coil from Alieexpress. When it arrives I wonder what are measurements I could take to make sure iit is safe. For example: how/where can I measure if the primary coil and the condesators do properly discharge after it has been switched off and how fast?
Interestingly the primary coil of the coil I want to buy is made from isolated wire (means there is some sort of PVC shielding around it just like a normal household cable would have). Is then charge/discharge of the primary an issue at all?
