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?

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

Edit 2024–10.

At least they know the answer if they wanted it.

Why do flat Earthers exist? Why can’t I see the Sun at night? Is it because Earth is not flat?

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

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.

Why is my crush beautiful to me but not to others?

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

What are some reasons for the widespread dislike of President Trump? In your opinion, has he been a good or bad president?

The other is “what does a “fuse” do?”

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

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

If people in the UK hate Trump so much, why does he own golf courses there?

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

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

There are three different concepts here that are getting confused.

Why does my girlfriend keep asking me if I love her?

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

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

so, what happens?

Hello, I have a question about astral projection. I started to get interested in this a little while after my mum passed in april. I thought I may be able to see her and speak with her if I managed to achieve astral projection. Since this interest, every time i sleep on my back I go into sleep paralysis. However, I cant progress into astral projection because it is very scary for me as I feel like I'm suffocating when this happens. I panic and force myself to wake up. This only ever happened about once a year before this. It sometimes lasts a long time. This has happened about 3 times per week since my mum died, as mentioned on a previous post. I no longer try to go into it anymore(due to the suffocating feeling), but it still happens. I read that sleep paralysis is the pathway to astral projection. Why has this started to happen so frequently since simply taking an interest in it? Is this connected to the afterlife? I am concerned about it as I now cannot seem to stop this happening. Could it be my mum trying to communicate? Im asking due to more knowledge around this in this group.

This one hit behind the barn.

What do you think about a sister's love?

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

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.

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

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

First Sentence:

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

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

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

He then describes Rainy Season and Lightning.

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

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

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

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

(Dc diagram shown, AC is similar).

I post the exact comment here.

There are two important concepts here.

What does a fuse do?

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

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.

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

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

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

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

Here is a simplified AC power diagram.

[old diagram got deleted by accident]

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

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.

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.

What is lightning?

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.

Barnstars:

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

But it can get overloaded, and no longer works.

He then describes the function of a fuse.

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

He then asserts :

what exactly is a ‘surge’ protector?

This device then solves the entire problem.

A circuit breaker is similar, but is resettable.

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

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

“ 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”

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.

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

One

a photo is worth a thousand words.

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