Master Tony we are mere human beings. Please explain further in human terms.
i am also human....
1. isolation transformers to isolate your setup from meralco, the galvanic isolation helps a lot...
an EI core 240vac input to 240 vac output, isolation from the meralco power source gets rid of ground loops and minimized shock hazards, sizing should be the sum of all the power consumptions of your gears tallied, do a load schedule so you know what capacity you need.. EI cores are not wide bandwidth and helps in the emi/ rfi issues..avoid toroidal power traffos here...
2. emi/rfi filtering using ferrite chokes and X2 caps..
at the secondary side, heavy gauge wires on ferite, can be toroidal or EE types sink up rfi's that may be present...
3. NTC resistors in series with the line after the fuse...
these are round disk types that has a resistance of 4 to 10 ohms when cold but gets hot when current is passing thru it, this causes its resistance to go below an ohm, this device helps to lower turn on current surges....
https://en.wikipedia.org/wiki/Thermistor4. MOV's or metal oxide varistors to arrest line surges in excess of 240 volts, right after the fuse..
also a round disk type, this devices is an open circuit when ac voltages are normally below the threshold voltage f=of the device, rated for 250 volts means it is not activated at voltages 240 volts and below, but becomes a short when activated at voltages above 250 vac.....
https://en.wikipedia.org/wiki/Varistor5. line snubbers composed of a resistor in series with a cap right at the socket outlets..
http://www.cde.com/resources/catalogs/igbtAPPguide.pdffor three years in a row, i have displayed this at the Dusit show, placed in a corner, was never meant to call attention to itself, safety of your gears is the raison d'etre for this line conditioner, no, it does not make your system sound good, only safe...
sad to say, so called line conditioners sold in the market is lacking one or more elements than the setup i mentioned....
