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?

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

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

A circuit breaker is similar, but is resettable.

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

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.

What does a fuse do?

There are three different concepts here that are getting confused.

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

He then asserts :

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

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

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.

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

Why did my ex replace me so fast?

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

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

The other is “what does a “fuse” do?”

I post the exact comment here.

There are two important concepts here.

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

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

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

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

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

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

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

What do you think are the real reasons Matt Gaetz just withdrew his name for Attorney General in the upcoming Trump administration?

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

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

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

Are miracles real or do they just have natural explanations?

He then describes the function of a fuse.

Here is a simplified AC power diagram.

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

“ 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”

At least they know the answer if they wanted it.

This device then solves the entire problem.

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.

[old diagram got deleted by accident]

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

This is 'the assistant's answer'

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

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

What is lightning?

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

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

Upvotes:

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

First Sentence:

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

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

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

In schematic diagrams this is the symbol for a fuse:

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.

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.

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

so, what happens?

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

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

a photo is worth a thousand words.

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

But it can get overloaded, and no longer works.

This one hit behind the barn.

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

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

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

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

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.
