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 where the MOV conducts again, and dissipated the energy.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

This is where this question deviates from being a 'generic' question, and becomes more specific.

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.

This device then solves the entire problem.

One is “what exactly is in a ‘surge protector’ ? ”

What are some good inspirational movies?

These are simplified answers to the original question, and does not change anything I wrote above.

Here is a simplified AC power diagram.

So, the voltage could go up to 500 volts, and the fuse will not open up.

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

The MOV will conduct when the voltage exceeds 50% of line voltage.

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.

To a flat Earther, what's wrong with the idea that gravity is simply a force inherent to space which operates only in one dimension? Why do they go further and try to deny gravity rather than just saying it's different than physicists claim?

Can the fuse protect the electronic devices from lightning instead of a surge protector.

An AC voltage/ current source, and an ac inductive load.

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

With so much evidence supporting the flat Earth theory, why aren't more resources dedicated to studying it?

It seems Mohan does not understand the difference between a comment and an Answer.

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

What does a fuse do?

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.

Do women lack the mental strength to succeed at STEM? There seems to be few women at STEM and more women leave STEM after a time of working at it. How can it be just sexism if women aren't banned from entering?

For this case there are devices called Metal oxide varistors (MOV).

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.

He then asserts :

It also is a device that limits the change in current flow.

(Dc diagram shown, AC is similar).

But… the neutral is now “floating” because of the 1 ohm resistance.

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

Are you happy with your life?

At one ohm, the resistor has a maximum of 1 watt power.

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

There are three different concepts here that are getting confused.

In schematic diagrams this is the symbol for a fuse:

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

The third is lightning and “how it gets conducted into a home.”

the problem then depends on "how fast does the fuse operate?".

What is lightning?

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 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.

Because the load is inductive, the current lags the voltage.(by a bit).

He then describes Rainy Season and Lightning.

A fuse is a non-resetable over current circuit protector.

This one hit behind the barn.

A circuit breaker is similar, but is resettable.

but I think this circuit , shows a few more pieces.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

First Sentence:

This is 'the assistant's answer'

The other is “what does a “fuse” do?”

There are two important concepts here.

Now when you have a certain ac resistance, then a current flows in a loop.

I post the exact comment here.

He then describes the function of a fuse.

“ 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”

One

The bolt then partially travels down the line to your home.

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.

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

what exactly is a ‘surge’ protector?

a photo is worth a thousand words.

These devices are installed between the “hot” and “neutral” and protective ground.

[old diagram got deleted by accident]

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

At least they know the answer if they wanted it.

This is the picture of an electronic coil of wire wound around a core of magnetic material.

“ A fuse is a device which protects the (circuit) against overload and short circuit.”

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

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.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

But it can get overloaded, and no longer works.
