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?

A circuit breaker is similar, but is resettable.

so, what happens?

But it can get overloaded, and no longer works.

Why are there no fossils for the 'missing link' that connects our ancestors with other species? Is this a misconception or is there another explanation?

what exactly is a ‘surge’ protector?

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

Is it wrong that I picked to be a Christian (as a teenager/14-year-old) even with knowing all of the information about other religions/atheism?

He then describes the function of a fuse.

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

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

Why aren't there any Indian girls married to Chinese guys but Chinese girls married to Indian guys?

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

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

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

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

What is the reasoning behind conspiracy theorists claiming that there were multiple shooters involved in the JFK assassination?

Upvotes:

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

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

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

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

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

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

Does the National Health Service (NHS) in the United Kingdom diagnose rare conditions? If so, does it provide treatment for them as well?

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

He then asserts :

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

It is common sense that Joe Biden is ruining America and is unfit to be president, but why are the liberals still supporting him when Trump is obviously a much better fit for office?

He then describes Rainy Season and Lightning.

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.

What does a fuse do?

Reds Sign Wade Miley, Place Hunter Greene On Injured List - MLB Trade Rumors

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

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”

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

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

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

The other is “what does a “fuse” do?”

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

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

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

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

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

There are two important concepts here.

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

At least they know the answer if they wanted it.

What is lightning?

In schematic diagrams this is the symbol for a fuse:

(Dc diagram shown, AC is similar).

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

This device then solves the entire problem.

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.

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

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.

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

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

There are three different concepts here that are getting confused.

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

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

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.

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

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

Barnstars:

This is 'the assistant's answer'

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

Here is a simplified AC power diagram.

a photo is worth a thousand words.

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

[old diagram got deleted by accident]

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.

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

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

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

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

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

I post the exact comment here.

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