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?

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?

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

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

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

How do flat earthers explain the Earth being stationary? Is this concept considered impossible?

There are two important concepts here.

One

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

Why do some men like older women?

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.

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.

What are your thoughts on RM's new album "Right Place, Wrong Person"?

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

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

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

I have a bad reputation and need help. What should I do?

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

I post the exact comment here.

The other is “what does a “fuse” do?”

What does pompano fish taste like?

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

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

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

How safe is it to travel to Kashmir in 2024?

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

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

He then asserts :

How much stronger is an average man than an average woman?

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

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.

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

I have a "fat pussy" and I'm super self cautions about it. Do guys think it's gross?

First Sentence:

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

This device then solves the entire problem.

Why am I so jealous towards couples? Why am I tired of being single and feel my life is over?

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 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.

What does a fuse do?

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

a photo is worth a thousand words.

How do you relax?

so, what happens?

In schematic diagrams this is the symbol for a fuse:

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

If Jesus was crucified by Governor Pontius Pilate, why does the Quran deny his death?

But it can get overloaded, and no longer works.

This one hit behind the barn.

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

Did another parent ever tell you something about your child that you didn’t know?

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

(Dc diagram shown, AC is similar).

At least they know the answer if they wanted it.

Are the seasons in Ireland different from those in Scotland, England, and Wales? Or are they just milder versions of each other?

Upvotes:

A circuit breaker is similar, but is resettable.

He then describes Rainy Season and Lightning.

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

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

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

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

There are three different concepts here that are getting confused.

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

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

[old diagram got deleted by accident]

Edit 2024–10.

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

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.

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

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

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

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.

Here is a simplified AC power diagram.

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

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.

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

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

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

what exactly is a ‘surge’ protector?

“ 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”

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

What is lightning?

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

He then describes the function of a fuse.

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

Barnstars:

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