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.

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

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

I feel so attached and in love with a dead celebrity. My love for anyone else is overshadowed by my love for him. What does this mean?

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

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

There are two important concepts here.

Do you think that drug addiction is a symptom of larger societal ills? What is it about our culture that leaves so many feeling like they're inadequate, trying any ill to find a cure?

what exactly is a ‘surge’ protector?

What is lightning?

What is treasury?

I post the exact comment here.

Here is a simplified AC power diagram.

(Dc diagram shown, AC is similar).

Does being poor build better character than being born rich?

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

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

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

Is it common for Americans to feel "trapped" due to the size and distance of their country from other countries/continents? Is this feeling an exaggeration or a reality?

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 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.

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.

Why are there so many illegal Haitians in Ohio? They can't walk here. Democrats flew them here to cause chaos and crime in Ohio.

This device then solves the entire problem.

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.

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

What does a fuse do?

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

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

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

so, what happens?

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

In schematic diagrams this is the symbol for a fuse:

A circuit breaker is similar, but is resettable.

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

How can one learn to talk frankly?

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

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

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

Time (physics): Who started counting our current time or is it just "set" by some scientific measure?

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

The other is “what does a “fuse” do?”

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

Is Jesus God almighty?

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.

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

There are three different concepts here that are getting confused.

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.

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

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

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

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

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

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

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

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

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

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

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

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

He then asserts :

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.

This is 'the assistant's answer'

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

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

He then describes the function of a fuse.

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

First Sentence:

Edit 2024–10.

“ 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”

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

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

a photo is worth a thousand words.

This one hit behind the barn.

But it can get overloaded, and no longer works.

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

He then describes Rainy Season and Lightning.

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