what exactly is a ‘surge’ protector?

At the secondary, it is 1000 times less.)turns ratio). If it gets hit with a 100,000 volt bolt of lightning then the voltage arrestors conduct and clamp the voltage down to line voltage, ( but a small amount leaks down the line). This is the problem.
But… the neutral is now “floating” because of the 1 ohm resistance.
A fuse is a non-resetable over current circuit protector.
So, the voltage could go up to 500 volts, and the fuse will not open up.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

He then describes Rainy Season and Lightning.
the problem then depends on "how fast does the fuse operate?".

so, what happens?
There is no harm in having the surge suppressor along with the fuse in the circuit. The fuse will not open up until the current melts the link. This will take time, and in the interim, that jolt will get transmitted into the power supplies.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”

A circuit breaker is similar, but is resettable.
The MOV will conduct when the voltage exceeds 50% of line voltage.
What does a fuse do?
What is lightning?
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
The third is lightning and “how it gets conducted into a home.”

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
but I think this circuit , shows a few more pieces.
These devices are installed between the “hot” and “neutral” and protective ground.

The bolt then partially travels down the line to your home.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

At one ohm, the resistor has a maximum of 1 watt power.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

This is where the MOV conducts again, and dissipated the energy.
There are three different concepts here that are getting confused.

One is “what exactly is in a ‘surge protector’ ? ”
This is 'the assistant's answer'
Once the voltage goes over 0.0650 volts, then this fact can be used to amplify the difference, and turn the circuit breaker off , furthur down the line. Essentially that is what a RCD/GFCI does, it compares the incoming current, to the outgoing current, and if the difference between the two currents is over 5mA, then it trips the circuit breaker.

At least they know the answer if they wanted it.
In schematic diagrams this is the symbol for a fuse:
It seems Mohan does not understand the difference between a comment and an Answer.
(Dc diagram shown, AC is similar).

Now when you have a certain ac resistance, then a current flows in a loop.
This is an electronic circuit designed to clamp voltages so that the Voltage Potential that appears at the outlet is never going to exceed the nominal value.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

There are two important concepts here.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
It also is a device that limits the change in current flow.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

Lightning arrestor is a spark-gap device, and can be installed anywhere. What is important, is that the wire is thick enough to withstand the lightning bolt and conduct the energy away from the building.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
An AC voltage/ current source, and an ac inductive load.
These are simplified answers to the original question, and does not change anything I wrote above.
Here is a simplified AC power diagram.
He then describes the function of a fuse.
Because the load is inductive, the current lags the voltage.(by a bit).
For this case there are devices called Metal oxide varistors (MOV).

This device then solves the entire problem.
I post the exact comment here.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
Upvotes:
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

a photo is worth a thousand words.
The other is “what does a “fuse” do?”
This is where this question deviates from being a 'generic' question, and becomes more specific.
Edit 2024–10.

“ A surge suppressor is the one which is connected at the input supply so that when there is a sudden change voltage it bypasses thereby protecting the (circuit) and electronic components”
But it can get overloaded, and no longer works.
This is a high voltage low current spike that comes down the line because of the power poles being struck, and the voltage suppressors activating on the primary side of the transformer.
