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?

At least they know the answer if they wanted it.

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

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, what happens?

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

What is lightning?

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

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

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.

I post the exact comment here.

Barnstars:

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

But it can get overloaded, and no longer works.

This is 'the assistant's answer'

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.

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.

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

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

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).

Hello,hope y'all doin good, i came to Quora to share my strange story , a very weird one , a story when luck smiled at me ,maybe u will enjoy it , let's begin,have fun... A year ago ,I was a real porn addicted(btw I was 18) ,but never had sex before, I don't have a gf I didn't try to find one even ,always thinking to go to find a sex worker but then I just don't , everyday watching different bodies getting fucked and everyday enjoying. One day, I was watching porn, a big ass lady with big boobs ,just after seeing her the image of my female cousin poped in my mind, (let's introduce her : she's 35 years old , very big ass , nice boobs ,not very big but nice,always wearing tight clothes , she's divorced ) and I thought of me fucking her ,I never had sexual desires for her but now I do days went by and when I met her I was so horny ,I couldn't stay with the family cz my penis was clearly erected , I realized this is my first time I get horny for one of my family ,it not illegal in my country.well to make a long story short( if u want details just text me I will tell u 😊),I decided to give her signs that I want to fuck her,finally I decided to have sex and with my cousin , I thought it is the best beggining for me, i started touching her when I came across her in a narrow place , make her feel my hard cock when we hug , I thought it will hard and I will be ashamed but no , I felt nothing and she said nothing , probably she thought it was by mistake,anyways, I decided then to talk with her about sex, waited for her to be alone in a room and talk with her, I confessed everything about me watching porn and addicted..etc,she said it's normal and u are growing up and u must have sex,well at that time I was like whaaat????? Well I didn't control myself and asked her for sex ( horny like I Ve never been before) she said that she will think Abt it ,2 weeka went by then she called me ,telling that she reserved a room in a hotel and we meet tonight ,we met,and bruuhh, sex is great , I mean, I had to find a pirstitue ,what I was waiting for to have such a feeling ????, I will never forget that night, I started kissing her she was kissing hard ,she misses sex so bad , she sucked my dick and swallowed my semen ,I felt I'm in a dream , then when fucked ,her ass was very big and the anus was open ,didn't struggle to get my hard cock inside it , she was obviously missing sex , she was shouting ,fuck me yh fuck me , I go fast after every word until I cum , we did that 3 times , then we went to her pussy , using condoms I fucked her so hard the moans were higher , everything was perfect ,in the end I asked her to lick her body , licked pussy ,ass, boobs,then she sucked my cock until we sleeped ,all I know that she was dirty ,well before even having sex with her I knew she is an open minded woman , and a woman that looks that she donesnt know anything , but she knows everything, but never expected having sex with her ,well she was horny and that helped...but no one of us regretted that sex ever.. We still have sex from time to time ,and I started having sex with sex workers , joining threesomes..etc If u want pics of her text me.

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

(Dc diagram shown, AC is similar).

He then asserts :

2024–10–14 [Omar Gharbi Omar Gharbi ]

Why is it so hard to date nowadays?

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

what exactly is a ‘surge’ protector?

He then describes Rainy Season and Lightning.

10 Times AI And Robots Have Already Done Horrible Things...Including Killing People - BuzzFeed

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

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

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

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

There are two important concepts here.

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

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.

Upvotes:

What does a fuse do?

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

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

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

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

2024–10–10[John johnson John Johnson ]

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

There are three different concepts here that are getting confused.

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

This one hit behind the barn.

[image of Common-mode choke]

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

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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

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

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

This device then solves the entire problem.

First Sentence:

eight

One is “what exactly is in 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.

The other is “what does a “fuse” do?”

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

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

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

A circuit breaker is similar, but is resettable.

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

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

He then describes the function of a fuse.

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

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

a photo is worth a thousand words.

In schematic diagrams this is the symbol for a fuse:

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

“ 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”

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.

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