What can you recommend as a non-linear load? Preferably one that can be bought or constructed inexpensively. Thank you!

Robbiel Factor said:Oh didn't notice the typo. Its for a 230/115 single phase transformer. We would just like to have a non-linear load test on the transformer we made and are looking for possible loads that are non-linear. It is so that we can analyze the harmonics that are occurring when our transformer is connected to a non-linear load.
You'll of course look at the current waveform with a spectrum analyzer? - you can't distort line voltage very much so you'll have to FFT current... it's loads of fun.. Get a cheap microphone and 'listen' to household appliances, too . Harmonics... on the cheap...Robbiel Factor said:It is so that we can analyze the harmonics that are occurring when our transformer is connected to a non-linear load.

A non-linear load is an electrical load that does not have a linear relationship between the input voltage and current. This means that the current and voltage are not in phase and can cause distortion in the power supply.
An inexpensive non-linear load is needed because linear loads, such as resistors, can be expensive and inefficient in converting electrical energy into other forms of energy. Non-linear loads are often used in electronic devices and power supplies as they are more cost-effective and efficient.
A linear load has a linear relationship between the input voltage and current, meaning that the current and voltage are in phase. On the other hand, a non-linear load does not have a linear relationship between the input voltage and current, resulting in distortion of the power supply.
Some examples of non-linear loads include computers, televisions, fluorescent lighting, and other electronic devices that use switching power supplies. These devices use non-linear components such as diodes, transistors, and capacitors to convert the AC power supply into DC power.
The right non-linear load for 230/115 voltage will depend on the specific needs and requirements of your application. It is best to consult with a professional or do thorough research to determine the appropriate load for your specific voltage and budget. Some factors to consider include power rating, input and output voltage, and efficiency.
