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?

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

This one hit behind the barn.

I post the exact comment here.

Hello I am 17 year old boy and I am interested in transgender why?

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

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

Here is a simplified AC power diagram.

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

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

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

In schematic diagrams this is the symbol for a fuse:

How can I navigate a romantic relationship as a trans person, and what are some common challenges that I might face?

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

(Dc diagram shown, AC is similar).

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

Why can't we send flat Earthers to space and show them the shape of Earth?

A circuit breaker is similar, but is resettable.

What is lightning?

What does a fuse do?

How do I stop having work crushes because I only keep getting disappointed almost every day as I keep seeing they don’t like me back and won’t ever ask me out?

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

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

The bolt then partially travels down the line to your 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.

What would have happened if Shin was a good movie instead of a bad one?

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

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

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

Can it be true that people know your name, not your story, they’ve heard what you’ve done, but not what you’ve been through, so take their opinions of you with a grain of salt?

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

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.

The other is “what does a “fuse” do?”

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

Why is Prince Harry being fired by BetterUp CEO Alexi Robichaux, and what role did Marc Benioff’s decision to pull sponsorship play in this?

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

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

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

Are rich people harder workers than poor people as a whole?

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

There are two important concepts here.

Edit 2024–10.

This is 'the assistant's answer'

He then describes the function of a fuse.

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

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

There are three different concepts here that are getting confused.

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

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.

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.

He then describes Rainy Season and Lightning.

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

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

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

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

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

Barnstars:

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

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

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

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:

“ 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”

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

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

He then asserts :

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

a photo is worth a thousand words.

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

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

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

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

This device then solves the entire problem.

so, what happens?

One

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.
