When I plug my NST into the wall at 60 Hz, I've been told a 120 Hz AC current comes out of my NST. What happens if I modulate the input frequency with a function generator to the transformer?

StrongForce said:I'm quite aware of the dangers and how to avoid them, what about using a simple function generator after wards to modulate the frequency. I just want a high voltage ac that I can modulate the frequency of.

A high voltage NST (neon sign transformer) is a type of electrical transformer specifically designed to produce high voltage alternating current (AC) at a relatively low current. It is commonly used for powering neon signs and other high voltage devices.
Changing the frequency of the AC output can affect the voltage and current levels of a high voltage NST. Higher frequencies typically result in higher voltages and lower currents, while lower frequencies produce lower voltages and higher currents. However, the exact effect may vary depending on the specific design and construction of the NST.
Playing with the frequency can be used for various purposes, such as adjusting the output voltage and current levels, or creating different effects in devices powered by the NST. It can also be used for experimental or educational purposes, to better understand the behavior of high voltage transformers.
As with any high voltage experiments, playing with the frequency on a high voltage NST can be dangerous if proper precautions are not taken. It is important to have proper training and knowledge of electrical safety, as well as using appropriate protective equipment, when working with high voltages.
Changing the frequency of a high voltage NST may potentially damage the transformer if not done carefully. It is also important to be aware of potential risks such as electrical shocks, burns, and fire hazards. It is recommended to only perform these experiments under the supervision of a trained professional.
