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.

First Sentence:

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

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

Here is a simplified AC power diagram.

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

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

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

He then describes the function of 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.

There are two important concepts here.

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

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

what exactly is a ‘surge’ protector?

There are three different concepts here that are getting confused.

What's it like to have an IQ of 140 to 170? Do people notice you're different?

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.

Im happy but there is a heavy feeling of sadness in my heart that I just can't remove. Why am I like this?

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

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

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

Brain ‘Reset Wave’ May Explain How ECT Rapidly Relieves Depression - Neuroscience News

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

What is lightning?

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

If you were to write a book about being a K-pop fan, what would the last sentence be?

A circuit breaker is similar, but is resettable.

I post the exact comment 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”

Bucheron and Myriel’s Karyn Tomlinson win James Beard Awards - Star Tribune

“ 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.

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 least they know the answer if they wanted it.

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

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

He then describes Rainy Season and Lightning.

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

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.

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

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.

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

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.

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

The other is “what does a “fuse” do?”

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.

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

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

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

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.

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

He then asserts :

This is 'the assistant's answer'

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

This one hit behind the barn.

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

But it can get overloaded, and no longer works.

[old diagram got deleted by accident]

so, what happens?

a photo is worth a thousand words.

In schematic diagrams this is the symbol for a fuse:

This device then solves the entire problem.

but this device (an Inductor) … impedes the rapid changes in the current.

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

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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

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

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

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

This is where the MOV conducts again, and dissipated the energy.
