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?

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

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

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

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

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.

This one hit behind the barn.

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

I post the exact comment here.

Has anyone ever participated in a gang bang and what was it like?

What do you think of Andrew Tate?

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

what exactly is a ‘surge’ protector?

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

Why did Kamala say immigrants eating cats isn’t real when there’s police bodycam footage of it happening?

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.

What does a fuse do?

What is the moral stance on lying? Can you provide examples of when it is appropriate or inappropriate to lie? Does the Bible address this issue?

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.

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

If James Bond is meant to be the best secret agent in the world, how come all the bad guys in the World seem to know who he is?

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.

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

There are two important concepts here.

How is Sola Scriptura incoherent?

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

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

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

According to Trump, Ukraine started the war. Why?

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.

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

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

a photo is worth a thousand words.

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

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

“ 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”

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.

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

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

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

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.

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

Here is a simplified AC power diagram.

so, what happens?

[old diagram got deleted by accident]

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

What is lightning?

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.

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

He then asserts :

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

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.

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

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

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

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

This device then solves the entire problem.

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

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

This is 'the assistant's answer'

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

The other is “what does a “fuse” do?”

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

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

(Dc diagram shown, AC is similar).

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

A circuit breaker is similar, but is resettable.

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.

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

But it can get overloaded, and no longer works.

There are three different concepts here that are getting confused.
