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?

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

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.

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

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 circuit breaker is similar, but is resettable.

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

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

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

“ 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”

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

so, what happens?

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

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

Im a 14 year old girl who doesnt want to wear a hijab but my parents force me to wear one. It makes me dislike it more. Im not ready for one no matter what people say and they get really mad at me. I have bad grades and no motivation. What do I do?

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

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

There are three different concepts here that are getting confused.

What kind of person makes you think "how come there are people like that"?

What is lightning?

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

He then describes Rainy Season and Lightning.

What is your review of "Regent", episode 5 of Season 2 House of the Dragon?

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.

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

(Dc diagram shown, AC is similar).

Here is a simplified AC power diagram.

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

How would you advertise if you wanted to be a "tour guide" who can take you through the dark web while warning you what not to look at and not to click on?

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

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

what exactly is a ‘surge’ protector?

Has the current political environment caused Canadians to cancel trips to the United States?

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

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

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

I post the exact comment here.

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

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.

First Sentence:

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.

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

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

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

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

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

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

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

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

This one hit behind the barn.

There are two important concepts here.

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

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

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.

The other is “what does a “fuse” do?”

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

He then describes the function of a fuse.

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

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

At least they know the answer if they wanted it.

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

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

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

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

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

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

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

He then asserts :

This device then solves the entire problem.

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.
