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?

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

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

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.

I like this guy and his personality is AMAZING. He’s everything I want EXCEPT I’m not 100% attracted to him. I’ve dated some really hot guys and I’m wondering if that’s ruined dating for me? What do I do?

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.

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

Why should the US public listen to Lauren Boebert, the queen of hypocrisy tell us, "We need morals back in our nation" when her real-time video is the heartbeat of immoral? Why does her audio not match her video?

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

Here is a simplified AC power diagram.

The other is “what does a “fuse” do?”

As a NATO/Ukraine supporter, since you're so blown away and angered by Trump putting Zelensky in his place yesterday, why don't you support the Ukraine by joining the Ukrainian army? There's 200,000,000+ of you. Put your money where your mouths are.

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

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

He then asserts :

He then describes the function of a fuse.

What does a fuse do?

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.

My son died seven months ago at the age of 24 how do I know if he’s in heaven and can he see me and hear me and why have I not gotten any signs yet from him or Mom just not seeing the signs how do I know if he’s OK how do I know if he’s happy?

what exactly is a ‘surge’ protector?

[old diagram got deleted by accident]

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

Why am I peeing so much without drinking a lot of water? I checked my blood sugar and it is normal. Could it be something else?

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

First Sentence:

What do flat Earthers think causes the "magical downward force"?

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

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

Why am I sweating so much when I try to do anything?

What is lightning?

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

[image of Common-mode choke]

What, when building a house, are the necessary wires (beside 120v) to future proof my house, Cat6, Coax, low voltage, and alarm wires?

This device then solves the entire problem.

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).

What are some good Caribbean islands to travel to with friends or family? Why?

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

Upvotes:

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

Can Donald Trump use the Alien Friends Act of 1798 to give ALL illegal immigrants an ultimatum: You have 1 month to leave America, after which you will be arrested and jailed for 3 years?

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

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

This is 'the assistant's answer'

What is the significance of Pete Rose, the all-time hits leader in Major League Baseball, who just passed away?

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

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

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

Have you ever accidentally found out that you were about to be fired?

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

“ 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”

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

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

There are two important concepts here.

(Dc diagram shown, AC is similar).

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

This one hit behind the barn.

There are three different concepts here that are getting confused.

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.

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

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

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

But it can get overloaded, and no longer works.

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

One

Edit 2024–10.

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

I post the exact comment here.

A circuit breaker is similar, but is resettable.

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.

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

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

He then describes Rainy Season and Lightning.

At least they know the answer if they wanted it.

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.

a photo is worth a thousand words.

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

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

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

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

so, what happens?

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

Barnstars:

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