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?

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.

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

I’m 26 years old and a married woman. My husband hates my flat chest. What is the permanent solution?

There are three different concepts here that are getting confused.

This one hit behind the barn.

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

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

What is the difference between anxiety and depressive neurosis?

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.

This device then solves the entire problem.

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

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

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

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

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

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

How do you know if your husband loves you truly and deeply?

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

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.

He then asserts :

Why is there a "double standard" applied to sex between a dog and a human? Why is it that to many who are at least mildly okay with bestiality, a WOMAN having sex with a male dog is fine, but a guy with a female dog is not?

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

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.

He then describes Rainy Season and Lightning.

Why do I feel sleepy after massage?

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

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.

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

(Dc diagram shown, AC is similar).

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

The other is “what does a “fuse” do?”

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

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

a photo is worth a thousand words.

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

[image of Common-mode choke]

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

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

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 it can get overloaded, and no longer works.

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

First Sentence:

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

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

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

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

This is 'the assistant's answer'

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.

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 a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

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

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

Upvotes:

so, what happens?

There are two important concepts here.

A circuit breaker is similar, but is resettable.

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.

“ 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”
