How Does High Voltage Transformer Works?
You can come across many different kinds of voltage transformers. In case of high voltage transformer, it works with high voltages. In general, these voltage transformers are used in power moving tools, where voltage are high sufficient to present a safety exposure. Microwave is the best example where high voltage transformer is used in household products. It is identified that high voltage transformer are the muscle of any microwave oven. With an input of 120 VAC (or 240 VAC in many of the commercial models) applied to the initial windings, the step-up transformer move up the initial voltage to extremely high voltage. It is then the high voltage is boosted even higher by the voltage-doubling action of the capacitor and as well with the diode.
You can confirm and there is actually no widely agreed definition for a high voltage transformer, even though some industry principles do spell out a variety of minimum voltages. These definitions are usually based on security considerations or the voltage where arcing would occur. It would be expedient if high voltage transformer was, widely accepted to begin at a good round number. Instead, it is seen that voltages as low as 5V recognized to as high voltage, in according to the Bonneville Power Administration, to be measured high voltage, it requires to be 100kV or above.
High voltage transformers are generated to manage with high amounts of electrical energy in the range of 600 to 5,000 volts, even though custom voltage transformers are on hand as well. A kind of device transformer, high voltage transformers are usually used for metering and security in high-voltage circuits and in electrostatic industrial and other technical applications. Because they have the capability to step up initial voltage to an extremely high voltage, they are frequently as well referred to as a power transformer.
Due to the high voltage and frequency that it has to manage, a high voltage transformer has appreciably different core geometry, winding methods, and padding techniques those ordinary transformers. For example, elements such as the volts/turn ratings of the secondary wire, insulating material dissipation, and other corona level should be considered carefully.

What happens when the voltage across a diode is 0?
I know if the voltage across a diode is +, then the diode turns on, and negative, the diode turns off. What if the voltage difference is 0? meaning the + and - end of the diode are at the same voltage. Is that an on or an off?
by on I mean short circuit and off I mean open circuit.
The same thing that happens when the voltage across any passive component is zero. No voltage across a passive component, no current through it. Simple as that.
Voltage is the cause, current is the effect. Without voltage, there is no current.
Also, the device you described in the above statement is only true for the idealized diode. No real diode enables current to flow through it at such tiny voltages.
Look up IV characteristic curves for diodes, and see what really happens in the case of real diodes.
Many times, the real diode is approximated with the concept of a turn-on voltage, whereby if the applied voltage is less than the turn-on voltage, even if it is in the forward bias direction, no current can flow. And if it is greater than the turn-on voltage, then current can flow.
