Once you have your , don't just scroll through it. Use the HV Study Protocol :

Other good alternatives:

How do you produce 1,000,000 volts in a lab without creating a nuclear explosion? The HV lab relies on elegant circuits.

: The design of HV equipment is largely dictated by the management of electric field intensity (stress). If the stress exceeds a material's dielectric strength, breakdown occurs. Numerical Methods

You cannot trust a transformer straight out of the factory. It must be destroyed (non-destructively, we hope) in a lab.
