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?

One

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 'the assistant's answer'

Is it socially acceptable for individuals to wear clothing typically associated with the opposite gender? What are some reasons for or against this practice?

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.

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”

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.

What does a fuse do?

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

Why was Super Buu so afraid of having Fat Buu torn out and becoming Kid Buu if he was going to destroy the Earth even before his transformation?

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

What is lightning?

what exactly is a ‘surge’ protector?

Why is blood sugar ranging from 70-180 in a day and checked through a glucometer?

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

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.

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

Why are girls supposed to have a stereotypical "hourglass" body shape, and why if you dont have an "hourglass" body shape you get treated differently? It doesnt make any sense to me.

(Dc diagram shown, AC is similar).

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

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

Barnstars:

There are three different concepts here that are getting confused.

Here is a simplified AC power diagram.

What do most wives fantasize about?

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

A circuit breaker is similar, but is resettable.

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

First Sentence:

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

Why do women have sex with dogs?

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.

He then describes the function of a fuse.

What misfortune led to an important discovery?

At least they know the answer if they wanted it.

What are some mind-blowing facts about Michael Jackson?

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

[old diagram got deleted by accident]

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

Does being poor build better character than being born rich?

This one hit behind the barn.

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

so, what happens?

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.

Edit 2024–10.

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

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

There are two important concepts here.

He then asserts :

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

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.

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

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

The other is “what does a “fuse” do?”

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

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.

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

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.

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

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

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

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

This device then solves the entire problem.

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

eight

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

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

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

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

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

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

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

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

But it can get overloaded, and no longer works.

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

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

In schematic diagrams this is the symbol for a fuse:

He then describes Rainy Season and Lightning.

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

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

a photo is worth a thousand words.
