What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

This is the picture of an electronic coil of wire wound around a core of magnetic material.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

So, the voltage could go up to 500 volts, and the fuse will not open up.
I post the exact comment here.
He then describes the function of a fuse.

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
These devices are installed between the “hot” and “neutral” and protective ground.

What does a fuse do?
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

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.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
But… the neutral is now “floating” because of the 1 ohm resistance.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
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.
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.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
This is where this question deviates from being a 'generic' question, and becomes more specific.

the problem then depends on "how fast does the fuse operate?".
It seems Mohan does not understand the difference between a comment and an Answer.
The MOV will conduct when the voltage exceeds 50% of line voltage.

Here is a simplified AC power diagram.
A fuse is a non-resetable over current circuit protector.
In schematic diagrams this is the symbol for a fuse:

(Dc diagram shown, AC is similar).
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.
This one hit behind the barn.
What is lightning?
There are three different concepts here that are getting confused.
2024–10–14 [Omar Gharbi Omar Gharbi ]
A circuit breaker is similar, but is resettable.
The other is “what does a “fuse” do?”
There are two important concepts here.
“ 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”

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
He then describes Rainy Season and Lightning.
At one ohm, the resistor has a maximum of 1 watt power.
but this device (an Inductor) … impedes the rapid changes in the current.
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.
Because the load is inductive, the current lags the voltage.(by a bit).
At least they know the answer if they wanted it.
This device then solves the entire problem.
He then asserts :
First Sentence:
Upvotes:
Can the fuse protect the electronic devices from lightning instead of a surge protector.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
It also is a device that limits the change in current flow.
An AC voltage/ current source, and an ac inductive load.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
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.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
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.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
but I think this circuit , shows a few more pieces.
