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?

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

What is lightning?

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

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

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

Why does my girlfriend keep asking me if I love her?

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

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

How can I get a girlfriend? I am 26.

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

First Sentence:

But it can get overloaded, and no longer works.

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

What does a fuse do?

What is the best way to end a relationship with someone who has future plans with you?

A circuit breaker is similar, but is resettable.

“ 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”

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

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

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

The other is “what does a “fuse” do?”

Why are men ridiculously delusional in the women they want/approach? I'm not a troll. This is a real question. Why does a fat, pot bellied, unkempt, balding, stupid (ergo poor) man, tell a woman above his league that she isn't hot enough for him?

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

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

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.

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

(Dc diagram shown, AC is similar).

My boyfriend wants to break up over too many petty arguments. To me, they are molehills because I truly love him & don't really think twice about them. If he loved me would he work through it?

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

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

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

How would you feel if your friend confided in you that she is cheating on her husband, knowing that he loves her deeply? What emotional and ethical considerations would you grapple with in response to her revelation?

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

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

so, what happens?

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.

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.

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 is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

He then describes Rainy Season and Lightning.

Barnstars:

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

There are three different concepts here that are getting confused.

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

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

There are two important concepts here.

This is 'the assistant's answer'

Here is a simplified AC power diagram.

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

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

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

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

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.

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

He then asserts :

a photo is worth a thousand words.

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

This one hit behind the barn.

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

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

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

I post the exact comment here.

He then describes the function of a fuse.

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.

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

This device then solves the entire problem.

Edit 2024–10.

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

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.
