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.

This device then solves the entire problem.

When did bestiality first occur to you and how did it happen the first time? Was it a deliberate decision or it just happened and you allowed it?

I post the exact comment here.

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.

What is lightning?

Does pressing a girls boobs hurt?

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

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

so, what happens?

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

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

Why didn't people like the Game of Thrones ending?

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

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

A circuit breaker is similar, but is resettable.

What is the best case of “You just picked a fight with the wrong person” that you've witnessed?

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

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

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

How do I express sarcasm in non-dialogue text when writing a fiction novel?

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.

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 where the MOV conducts again, and dissipated the energy.

Why are flat Earthers made fun of when they seemingly don't exist? I have only met one flat Earther in 18 years.

But it can get overloaded, and no longer works.

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

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

Why do I get stressed when I go to bed?

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.

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

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

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

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

What does a fuse do?

Why cant I sleep even tho I am sleepy? I am not anxious or worried but my body just doesn't want to. I've been awake for almost 2 days and feel sleepy but I cant sleep. My doctor said its anxiety related but its not. Is this normal?

Edit 2024–10.

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.

(Dc diagram shown, AC is similar).

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

At least they know the answer if they wanted it.

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

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

In schematic diagrams this is the symbol for a fuse:

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

Barnstars:

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

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

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

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.

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

[old diagram got deleted by accident]

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

what exactly is a ‘surge’ protector?

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.

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

a photo is worth a thousand words.

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

This one hit behind the barn.

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

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).

Can the fuse protect the electronic devices from lightning instead of 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).

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

There are three different concepts here that are getting confused.

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

“ 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 other is “what does a “fuse” do?”

He then describes Rainy Season and Lightning.

He then asserts :

There are two important concepts here.

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

He then describes the function of a fuse.

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.

[image of Common-mode choke]

This is 'the assistant's answer'

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

First Sentence:

Here is a simplified AC power diagram.

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