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

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

There are three different concepts here that are getting confused.

How do I convince flat earthers that the earth is round?

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

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

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

Why do our deceased do not protect us from other bad spirits?

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

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

A circuit breaker is similar, but is resettable.

What is the sum of X+XX+XXX+XXXX?

At least they know the answer if they wanted it.

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

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

Atheists claim that Earth is 10 billion years old, yet there are no fossils that old. What do you have to say for yourselves for lying?

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

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

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

Did you know God exists? 900+ answers later and no atheist has yet to be successful. Day 8 of asking Atheists to provide a SINGLE argument that demonstrates a cause for the beginning of the universe while avoiding the problem of infinite regression.

I post the exact comment here.

In schematic diagrams this is the symbol for a fuse:

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.

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

My husband asked me why do I keep on complaining about him cheating. Why don't I just leave?

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

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.

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

This is 'the assistant's answer'

Is it possible to make cars that run on water instead of gasoline or other fossil fuels? Why haven't we done so yet?

There are two important concepts here.

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

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.

Have you ever been a victim of gaslighting? What happened?

What is lightning?

What does a fuse do?

He then asserts :

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.

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

The other is “what does a “fuse” do?”

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.

Upvotes:

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

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

But it can get overloaded, and no longer works.

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.

a photo is worth a thousand words.

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

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

He then describes the function of a fuse.

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

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

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

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

He then describes Rainy Season and Lightning.

“ 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”

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

(Dc diagram shown, AC is similar).

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

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

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

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

This one hit behind the barn.

so, what happens?

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

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

This device then solves the entire problem.

[old diagram got deleted by accident]

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.

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

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

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

what exactly is a ‘surge’ protector?

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

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