Homework Statement
I am trying to design a passive filter for a home power conditioning device. It is for a standard 120V 60Hz outlet with a 15A fuse. I have decided to go with 'pi' or 'T' filter, but I am having trouble locating the specifications needed to choose the necessary parts.
It is my understanding that I will be using a low-pass filter. I have also decided to use 3 220V rated Metal Oxide Varistor's between the lines in order to control voltage spikes.
The loads being attached will be both capacitive and inductive. For example, a television, computer, 3/4 HP motor. I plan to have 2 outlets connected to the device.
Any help would be appreciated.
Homework Equations
I understand that the equations of 2*Pi*F*L and XL/(XL + XC) are to be used in determining the input vs the output.
The Attempt at a Solution
It is my understanding that in order to calculate the parts, I need to know the characteristic impedance of the lines going in. I have searched on-line for specifications, but have not turned up anything along the lines of my design. I would like my design to use only passive components.
I do not wish for anyone to provide me with a solution, but if anyone can direct me to the information I am seeking, it would be greatly appreciated. I am just getting really frustrated trying to find the information, and any direction would be greatly appreciated.
