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?

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

There are two important concepts here.

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

Do you think cheating is that bad?

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

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

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.

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

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

A circuit breaker is similar, but is resettable.

Do you think there will ever be a movie that features a line such as “You graduated at the top of your class in liberal arts, we need your help”?

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

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

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

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

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

(Dc diagram shown, AC is similar).

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

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

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

How is it, in the USA, a country with 334 million people, the choice of President comes down to two aged men, one of whom is a liar as well as a criminal, one who appears to be on his way to dementia. Surely a democratic country can put up better?

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

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

This one hit behind the barn.

He then asserts :

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

Here is a simplified AC power diagram.

Why does my crush always looks at me in a sad way whenever I talk with other boys, and if he catch me staring on him then he go and flirt with other girls and then check if I am looking at him?

The other is “what does a “fuse” do?”

At least they know the answer if they wanted it.

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

(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.

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

Why do some young mothers trick a guy into believing that they're pregnant and it's their child when years later they find out that it's not even theirs should he still pay child support or not?

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

But it can get overloaded, and no longer works.

He then describes the function of a fuse.

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

a photo is worth a thousand words.

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.

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

what exactly is a ‘surge’ protector?

2024–10–10[John johnson John Johnson ]

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

Edit 2024–10.

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.

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

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

What does a fuse do?

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

This is 'the assistant's answer'

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

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.

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

What is lightning?

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

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.

Upvotes:

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

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

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

This device then solves the entire problem.

There are three different concepts here that are getting confused.

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

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

In schematic diagrams this is the symbol for a fuse:

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

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%).

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.

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 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”

so, what happens?

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

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