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?

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

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

The other is “what does a “fuse” do?”

Is there any truth to the claim that Kamala Harris got where she is by sleeping around, or is that just typical conservative bigotry?

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

Edit 2024–10.

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

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

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

Here is a simplified AC power diagram.

I post the exact comment here.

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

But it can get overloaded, and no longer works.

What did Rama tell Sita about Kaliyug?

He then asserts :

[image of Common-mode choke]

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

How do I cope with the fact that I will never have a girlfriend?

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

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.

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.

Why do narcissists and especially covert narcissists always play the victim?

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

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

What does a fuse do?

★ who are your favorite booktubers?

A circuit breaker is similar, but is resettable.

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

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.

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?

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.

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

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

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

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

Why is America so fucked up?

There are two important concepts here.

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

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

This is a real question: Why do a lot of men/boys hate (yes, hate) women that voice their criteria in choosing a partner? Even when the criteria is sane and responsible. Besides it being, sadly, an effective mating strategy, why does it exist?

He then describes the function of a fuse.

“ 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”

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.

This one hit behind the barn.

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

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

There are three different concepts here that are getting confused.

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

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

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

He then describes Rainy Season and Lightning.

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

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

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

First Sentence:

One

What is lightning?

This device then solves the entire problem.

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

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

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

Barnstars:

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.

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

At least they know the answer if they wanted it.

a photo is worth a thousand words.

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

so, what happens?

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

This is 'the assistant's answer'

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

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