Microsurges of over current happen a lot here, i can see it on my multi meter, apparently surge suppressor help with that by absorbing the extra current, which reduce the long term strain on all the electronic connected to it.
If you can see it on a multimeter, then it is not a surge. If you saw it on a multimeter, relevant numbers were posted. Hearsay is routine when one cannot provide numbers.
What is damaged by a micro surge? No number will be posted because propaganda invents a fear called micro surges - that never causes damage - that is undefined by a number - that cannot be measured by a meter. Anyone who first learned numbers would know that.
For example, how many volts does an ethernet suffer without damage? 2000 volts. A micro surge that is well below 2000 volts somehow causes damage? Yes - when someone does not attack their source for not providing honesty - a number. No numbers is how scam artists recruit the most naive. Honestly can only exists when numbers are provided.
Destructive surges are hundreds of thousands of joules. An effective protector connects something less than 50,000 amps low impedance (ie less than 10 feet) and harmlessly to earth. Then hundreds of thousands of joules dissipate harmlessly outside. Then micro surges also cause no damage. No numbers (and we all learned this from what promoted Mission Accomplished) are a first indication of scams and lies. Every honest recommendation also says where hundreds of thousands of joules are harmlessly absorbed. Always.
Where did he provide even one number that defines a micro surge? Show us a meter number that says otherwise.
Destructive surges are characterized by an 8/20 microsecond transient - another damning number. Learn this from any MOV datasheet. Meters can never measure that transients. Only the informed would know that. Numbers are ignored when ineffective (near zero) protection is recommended by myths and hearsay.
Micro surges are made irrelevant by protection already inside every appliance. How many clocks, GFCIs, dishwashers, LED bulbs, radios, TVs, and recharging devices are you replacing daily or weekly due micro surges? None? What needs protection from micro surges? Smoke detectors? What protects THE most important appliance when any surge exists? Best protection is already inside every appliance. Micro surge are irrelevant when reality and numbers exist.
An informed consumer earths a 'whole house' protector so that a typically destructive surge (and micro surges) do not cause damage. Most only know otherwise by ignoring spec numbers. The fewer and informed properly earth one 'whole house' protector. Then all surges cause no damage ... those damn spec numbers.
Protection from all surges (ie direct lightning strikes, micro surges, etc) has always been provided by properly earthing a 'whole house' protector such as one from Leviton. Protection increases with every foot shorter to earth AND with every foot of separation between protector and computer.
