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?

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

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

What is the meanest thing your husband has said to you?

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

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

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

Why do you write?

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 lightning?

What is a narcissist grandmother like, with her grandchild?

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

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.

There are three different concepts here that are getting confused.

Why is Russia always right? All eyes toward Russian glory!

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

He then asserts :

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

How was your JEE 2024 result like?

At least they know the answer if they wanted it.

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

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

He then describes Rainy Season and Lightning.

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

How can I be okay with being ugly? What is the bright side?

Here is a simplified AC power diagram.

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

The other is “what does a “fuse” do?”

What is the reasoning behind conspiracy theorists claiming that there were multiple shooters involved in the JFK assassination?

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

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

Barnstars:

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.

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.

But it can get overloaded, and no longer works.

Why would calling me an incel help anything? How does that solve anything? Why can’t you actually be helpful and offer productive honest advice?

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.

There are two important concepts here.

Can we see your heels?

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

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.

— fri(end)s forever!

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

[image of Common-mode choke]

This device then solves the entire problem.

How do you get started in bestiality with a dog as a male?

Edit 2024–10.

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

(Dc diagram shown, AC is similar).

Why does my mother care about my sister more than me?

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.

He then describes the function of a fuse.

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

Why don't we hear our own snoring?

2024–10–10[John johnson John Johnson ]

2024–10–16 [ OO OLAOYE OYEBODE ]

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

This one hit behind the barn.

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.

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

“ 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 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.

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

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

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

First Sentence:

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

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

This is 'the assistant's answer'

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

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

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

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.

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

In schematic diagrams this is the symbol for a fuse:

nine

eight

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

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

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

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

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

I post the exact comment here.

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

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

One

Upvotes:

what exactly is a ‘surge’ protector?

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

a photo is worth a thousand words.

[old diagram got deleted by accident]

so, what happens?
