Hi folks,
I will be building a HV DC power supply with current limitation to test the dielectric breakdown voltage between the primary and secondary of my transformers.
But, what should be, a safe current value in order not to carbonise the breakdown insulation spot?
I guess we need to calculate dissipated power per surface here? But what is the surface of an internal arc?
