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?

(Dc diagram shown, AC is similar).

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

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

What is the reason for The Acolyte (2024 series) having poor reception among Star Wars fans?

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

The other is “what does a “fuse” do?”

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

Why do liberals think same-sex marriage is alright? The Bible makes it very clear that it's not alright to be gay, why can't liberals understand that?

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

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

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

How do I develop the patience to read books?

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

There are three different concepts here that are getting confused.

A circuit breaker is similar, but is resettable.

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

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 exactly is a ‘surge’ protector?

Is a man who enjoys anal sex considered a sissy? For those who think so, why can't they be thought of as someone who enjoys a variety of sexual pleasure?

What does a fuse do?

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

I post the exact comment here.

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

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

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

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

Why do many people think that Japan is not a gay-friendly country whereas 72% Japanese support same-sex marriage (the same number as in the US)?

He then describes Rainy Season and Lightning.

Here is a simplified AC power diagram.

There are two important concepts here.

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

This is 'the assistant's answer'

First Sentence:

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.

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

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

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.

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

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

But it can get overloaded, and no longer works.

One

In schematic diagrams this is the symbol for a fuse:

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

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

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

This one hit behind the barn.

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.

At least they know the answer if they wanted it.

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

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

What is lightning?

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

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

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

“ 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”

He then asserts :

This device then solves the entire problem.

Edit 2024–10.

a photo is worth a thousand words.

Barnstars:

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

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

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.

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

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.

[old diagram got deleted by accident]

He then describes the function of a fuse.

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

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