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?

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 white women so overly emotional?

What does a fuse do?

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).

Why is it rare for someone to despise both the Democrats and Republicans?

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

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

I post the exact comment here.

so, what happens?

Why didn't people like the Game of Thrones ending?

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

(Dc diagram shown, AC is similar).

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.

It has been said that people with ADHD can often hyperfocus. Can that be an advantage?

This one hit behind the barn.

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

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.

Why would calling me an incel help anything? How does that solve anything? Why can’t you actually be helpful and offer productive honest advice?

He then asserts :

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

What is treasury?

Here is a simplified AC power diagram.

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

[old diagram got deleted by accident]

What is the best reply if your boyfriend asks you,"why do you love me?"

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

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

A circuit breaker is similar, but is resettable.

Why do most atheists in debates with theists take Bible verses out of context much of the time? Are they lying maliciously or do they not understand theology enough to understand the meaning?

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

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

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

What are some common lies that addicts may tell themselves?

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

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

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

One

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

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

Sorry, Trump supporters, but eventually it will have to be asked: Why didn't Trump do as well in his first term as he is doing NOW?

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.

Why all the fuss about Trump’s policy initiatives? Isn’t he just trying to set a moral tone for the Republican Party to make America great again?

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

Upvotes:

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

There are two important concepts here.

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.

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.

Can the fuse protect the electronic devices from lightning instead of 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.

Barnstars:

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

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

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

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

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

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

There are three different concepts here that are getting confused.

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

This is 'the assistant's answer'

He then describes the function of a fuse.

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

what exactly is a ‘surge’ protector?

At least they know the answer if they wanted it.

The other is “what does a “fuse” do?”

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

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?

“ 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”

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

In schematic diagrams this is the symbol for a fuse:

nine

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

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

Edit 2024–10.

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.

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

What is lightning?

This device then solves the entire problem.

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.

But it can get overloaded, and no longer works.

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

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

He then describes Rainy Season and Lightning.
