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?

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.

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

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

In your opinion, who is the most overrated singer/band/artist in modern music history and why?

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

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

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

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

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

Have you ever gone to a porn theater with your wife?

This device then solves the entire problem.

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

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

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.

First Sentence:

What is the story behind bhai dooj?

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

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

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

If you were president, how would you make America "great again?"

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

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.

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

Ive been pretending to be okay and acting as normal as possible, but Im actually completely heartbroken after a recent breakup. Its painful and really affecting me, to the point where I cant concentrate at work, Ive lost my appetite, I cant sleep, and It feels as if my whole world has been turned upside down. I loved him so much. He said so many cruel things to me and it made me realize he must not have loved me the way I loved him, or he wouldnt have said such horrible things. How do I handle the heartbreak and why cant I accept that he didnt love me and just forget about him?

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

Barnstars:

There are three different concepts here that are getting confused.

I'm straight, so why do I love watching guys cum?

Edit 2024–10.

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

At least they know the answer if they wanted it.

Is there anything wrong with me because I'm still single?

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

(Dc diagram shown, AC is similar).

What’s the worst thing you caught anyone in your family doing?

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

In schematic diagrams this is the symbol for a fuse:

A circuit breaker is similar, but is resettable.

so, what happens?

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

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

Here is a simplified AC power diagram.

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

This is 'the assistant's answer'

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

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.

a photo is worth a thousand words.

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

The other is “what does a “fuse” do?”

He then describes Rainy Season and Lightning.

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.

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

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

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

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

This one hit behind the barn.

I post the exact comment here.

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

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

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

He then describes the function of a fuse.

what exactly is a ‘surge’ protector?

There are two important concepts here.

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

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

“ 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”

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.

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

But it can get overloaded, and no longer works.

What is lightning?

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

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

What does a fuse do?

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

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