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?

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

“ 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”

Can I fix a fridge leak myself, or should I call a pro?

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

There are three different concepts here that are getting confused.

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

What is the most interesting question you can ask to get to know someone?

What is lightning?

There are two important concepts here.

eight

Why do I sometimes hear full conversations when I am alone?

[old diagram got deleted by accident]

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

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

Everyone says the pet population is out of control. Everyone says you MUST spay or neuter your pets. No one wants to talk about how its almost $1,000 to spay or neuter a pet. Why is it so expensive if its so necessary? Animal shelters do it for free.

What does a fuse do?

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

He then asserts :

Is it possible to make cars that run on water instead of gasoline or other fossil fuels? Why haven't we done so yet?

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

This is 'the assistant's answer'

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

How do individuals become targeted individuals? Is it solely due to experiencing stalking or harassment, or are there other factors involved?

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.

I post the exact comment here.

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%).

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

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?”

Republican Trump is a billionaire, president, won't be held accountable for multiple felonies, and pretty much has whatever he wants. So why is he always whining and crying about stupid, pointless stuff? Is he incapable of happiness?

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

Have you ever been forced to dress like a girl?

In schematic diagrams this is the symbol for a fuse:

a photo is worth a thousand words.

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

How do you feel about Donald Trump signing an executive order that says there are only two genders?

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

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

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

This device then solves the entire problem.

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

A circuit breaker is similar, but is resettable.

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

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

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

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?

so, what happens?

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

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

(Dc diagram shown, AC is similar).

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

He then describes Rainy Season and Lightning.

what exactly is a ‘surge’ protector?

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

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

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.

Barnstars:

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

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

One

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

He then describes the function of a fuse.

But it can get overloaded, and no longer works.

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

2024–10–16 [ OO OLAOYE OYEBODE ]

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

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

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

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

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

This one hit behind the barn.

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.

Here is a simplified AC power diagram.

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

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

nine

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

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.

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

[image of Common-mode choke]

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.

At least they know the answer if they wanted it.

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.

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