An AC power conditioner is the typical power conditioner that provides "clean" AC power to sensitive electrical equipment. Usually this is used for home or office applications and has up to 10 or more receptacles or outlets and commonly provides surge protection as well as noise filtering.
Power line conditioners take in power and modify it based on the requirements of the machinery to which they are connected. Attributes to be conditioned are measured with various devices, such as, Phasor measurement units. Voltage spikes are most common during electrical storms or malfunctions in the main power lines. The surge protector stops the flow of electricity from reaching a machine by shutting off the power source.
The term "Power Conditioning" has been difficult to define historically. However, with the advances in power technology and recognition by IEEE, NEMA, and other standards organizations, a new actual engineering definition has now been developed and accepted to provide an accurate depiction of this definition.
"Power Conditioning" is the ability to filter the AC line signal provided by the power company. "Power Regulation" is the ability to take a signal from the local power company, turn it into a DC signal that will run an oscillator, which generates a single frequency sine wave, determined by the local area needs, is fed to the input stage of power amplifier, and is then output as specified as the ideal voltage present at any standard wall outlet.
