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).

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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.

I refuse to date any women that are social media influencers, content creators, TikTok celebrities, and use Only fans. Would this be seen as normal, or would I be going too far? Why?

Barnstars:

What would happen if the Soviet Union had simply annexed Manchuria after World War 2 or kept it independent as a puppet state allied them and separate from China as China was too weak too oppose it anyway?

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

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

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

Why is there so much free porn on the internet?

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

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.

Why are we explaining today’s “climate change” as driven by human related “green house” gasses when natural “global warming” pushed sea level up to the “shores” of Topeka with no human contribution or even presence? Is Occam’s Rasor applied?

(Dc diagram shown, AC is similar).

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

How many couples swap wives?

a photo is worth a thousand words.

A circuit breaker is similar, but is resettable.

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

Do you regret being married to your current wife?

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

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

Why have Indian girls almost stopped wearing sarees?

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

What is lightning?

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

What made you stop being an addict?

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

so, what happens?

He then asserts :

What if Homelander turned out to be a good guy instead of an evil milk drinking manchild? Nobody seems to touch on this much.

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

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

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

Do narcissists love their children?

I post the exact comment here.

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

First Sentence:

What is the meaning of xx in texting?

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.

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

Why do some young mothers trick a guy into believing that they're pregnant and it's their child when years later they find out that it's not even theirs should he still pay child support or not?

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

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

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 told my 13-year-old daughter that she should never start a fight, but has my permission to end it. She got suspended for ending a fight that some other girl picked with her by hitting her then retreating. How do I handle the school’s response?

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

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

what exactly is a ‘surge’ protector?

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

eight

This one hit behind the barn.

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

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

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

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

But it can get overloaded, and no longer works.

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 other is “what does a “fuse” do?”

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.

Here is a simplified AC power diagram.

He then describes the function of a fuse.

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

This device then solves the entire problem.

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

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

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

What does a fuse do?

[old diagram got deleted by accident]

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

In schematic diagrams this is the symbol for a fuse:

This is 'the assistant's answer'

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

nine

At least they know the answer if they wanted it.

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

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.

“ 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”

There are three different concepts here that are getting confused.

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

He then describes Rainy Season and Lightning.

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

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

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

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.

There are two important concepts here.
