so, what happens?
First Sentence:
How has Sanskrit influenced modern Tamil language, particularly in terms of vocabulary?
what exactly is a ‘surge’ protector?
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.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.

Because the load is inductive, the current lags the voltage.(by a bit).
This device then solves the entire problem.

But… the neutral is now “floating” because of the 1 ohm resistance.
My ex moved on so fast. How can I overcome the pain?
At one ohm, the resistor has a maximum of 1 watt power.
but I think this circuit , shows a few more pieces.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
This is where the MOV conducts again, and dissipated the energy.

The third is lightning and “how it gets conducted into a home.”
The MOV will conduct when the voltage exceeds 50% of line voltage.
This is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

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.

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
Barnstars:
So, the voltage could go up to 500 volts, and the fuse will not open up.

In schematic diagrams this is the symbol for a fuse:
What is lightning?
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

“ A fuse is a device which protects the (circuit) against overload and short circuit.”
It also is a device that limits the change in current flow.
Here is a simplified AC power diagram.

It seems Mohan does not understand the difference between a comment and an Answer.
This is where this question deviates from being a 'generic' question, and becomes more specific.
A circuit breaker is similar, but is resettable.
This one hit behind the barn.

Now when you have a certain ac resistance, then a current flows in a loop.
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.
What does a fuse do?
There are three different concepts here that are getting confused.
But it can get overloaded, and no longer works.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
I post the exact comment here.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
a photo is worth a thousand words.

The bolt then partially travels down the line to your home.
the problem then depends on "how fast does the fuse operate?".
One
[image of Common-mode choke]
A fuse is a non-resetable over current circuit 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.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
At least they know the answer if they wanted it.
These devices are installed between the “hot” and “neutral” and protective ground.
He then asserts :
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
He then describes the function of a fuse.
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.
The other is “what does a “fuse” do?”

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.
Upvotes:
For this case there are devices called Metal oxide varistors (MOV).
One is “what exactly is in a ‘surge protector’ ? ”
but this device (an Inductor) … impedes the rapid changes in the current.
This is 'the assistant's answer'

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
(Dc diagram shown, AC is similar).
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
“ 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”
There are two important concepts here.
