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?

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

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

He then describes Rainy Season and Lightning.

Why is Trump not on a violation of probation, offering a job for an endorsement is in violation of federal law? Kaamala knew better she is very sharp.

What is lightning?

What does a fuse do?

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

I’ve often wondered why fans aren’t deployed on GBBO during warm weather? I’ve seen too many desserts melt (and bakers too…). (I live in Pompano Beach and we try to use fans in lieu of AC as much as possible).

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

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

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

In what ways is Bollywood becoming westernized?

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

But it can get overloaded, and no longer works.

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.

Do Flat Earthers exist today? If so, where do they live?

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

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

what exactly is a ‘surge’ protector?

Its year 2041, and president Hunter Biden has ordered every republican who sweared at him to be arrested and shot. I am on my way to the death row listening to the cheer of the Liberal mob chanting death death death. How can I escape?

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

A circuit breaker is similar, but is resettable.

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

I am glad you enjoyed my pictures. Do you have any photos to share?

This device then solves the entire problem.

This one hit behind the barn.

Why do narcissists avoid talking about the real issues?

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

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 “.

Why do I sweat a great deal while exercising the same on some days and not so much on others?

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.

How did you become popular in school?

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

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.

Hi, I’m Jo. My best friend died 2 years ago today. My husband died 6 months later. So, I’m a depressed mess (we were married 28 years) and can’t shake it. Even my Brother is worried. Some days I don’t do anything, and avoid men cause I don’t want to date. Any suggestions? Thanks for reading.

There are three different concepts here that are getting confused.

[old diagram got deleted by accident]

This is 'the assistant's answer'

How can the democrats say Mr. Trump is bad when he is already fixing this country again and he's not even president yet?

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

He then describes the function of 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.

Can bosses get fired for being too hard on employees?

One

He then asserts :

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.

Atheists who said that reading the Bible made them an atheist, how? Literally there are millions of people who read the Bible daily and still believe in God. So why say that? I mean unless you want to sound smart & edgy

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

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

The other is “what does a “fuse” do?”

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

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

[image of Common-mode choke]

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.

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

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

Edit 2024–10.

Barnstars:

First Sentence:

“ 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”

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

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

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

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.

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).

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

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

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

At least they know the answer if they wanted it.

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

a photo is worth a thousand words.

There are two important concepts here.

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

I post the exact comment here.

Here is a simplified AC power diagram.

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

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

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

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

so, what happens?

(Dc diagram shown, AC is similar).

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

nine

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

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

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

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.
