You may be right about the dynamic current but the company insists no current is impeded by the filter design
I don't understand why you are grouping filtering (noise) with appliance protection (surges). These are two completely different topics with different solutions.
An equivalent circuit inside your $100 garden variety protector also sells in Wal-Mart for $7. Why the price difference? Did you read the manufacturer spec numbers? Surge protectors are some of the easiest scams to promote. That $100 protector does not claim to protect from a typically destructive surge. But it does protect from some surges that are not destructive. That near zero protection is just enough to advertise it as 100% protection.
Nothing stops a surge. Will 2 centimeter MOVs or tiny passive filters in a Zerosurge stop what three miles of sky could not? Again, that ‘stopping’ is what so many believe due to advertising and hearsay.
A protector adjacent to electronics can only do two things. Either stop a surge. Or absorb the energy. How many joules in that $100 protector? Destructive surges are hundreds of thousands of joules. What will hundreds of joules in that expensive protector do? Some adjacent protectors even create house fires as recently discussed by ramjet33 on 6 Jun 2012 in "My 110 Tall had a fire over the weekend!"
After placing a 911 call and getting the kids situated, I found the fire behind the tank in the dining room. …
The fire investigator says a build up of moisture in the surge protector faild the circuit and superheated to combustible limits. WOW. … And the UL listed SP was still able to hold a charge enough to super heat the plastic to get flaming.
A solution used in any facility that can never have damage will cost you maybe $1 per protected appliance. Comes from companies with better reputations such as Leviton, General Electric, ABB, Square D, Intermatic, and Siemens - to name only a few. Companies that any ‘guy’ knows as responsible. This one ‘whole house’ protector must be located within feet of earth ground. It has a wire to make that always required connection to earth. A Cutler-Hammer version sells in Lowes and Home Depot for less than $50.
A ‘whole house’ protector also has spec numbers that define protection even from direct lightning strikes. Lightning may be 20,000 amps. A minimally sized ‘whole house’ protector is 50,000 amps. Because only effective protectors earth destructive surges. And remain functional.
Most all anomalies (even interior generated surges) are made irrelevant by protection already inside every appliance. Your concern is a rare anomaly that can overwhelm that protection. That occurs maybe once every seven years. That is the reason for protectors. It helps when the protector claims to protect from that anomaly. Read spec numbers for that $100 profit center.
One ‘whole house’ protector properly earthed (earthing – not the protector – is more important) means even less surges (including interior generated ones) are made irrelevant. What is always found in every facility that cannot have damage? A properly earthed ‘whole house’ protector. That superior solution is also your least expensive option. Even that $100 garden variety protector needs the well proven ‘whole house’ protection.
