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

In schematic diagrams this is the symbol for a fuse:

What happened to the American Russell Bentley from Texas that was fighting for the pro-Russian commies?

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

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

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

A circuit breaker is similar, but is resettable.

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

He then asserts :

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

“ 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”

I post the exact comment here.

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

Here is a simplified AC power diagram.

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

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

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

Can AI kill MBA jobs even if MBA is done from Ivy league universities? What should one pursue AI/ML from IIT or MBA from IIM in terms of better opportunities/wealth and career growth/duration?

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

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.

The other is “what does a “fuse” do?”

But it can get overloaded, and no longer works.

How can someone in your family purposely try to destroy your reputation?

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

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

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

Hic perferendis in et impedit quo.

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

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

(Dc diagram shown, AC is similar).

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

Do women like men who have slept with many women?

What does a fuse do?

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.

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

Are today’s baseball pitchers faster than a few years ago, or is it that radar guns have improved and get the pitch speed as it is released rather than as it reaches the plate?

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

First Sentence:

so, what happens?

This device then solves the entire problem.

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

This is 'the assistant's answer'

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.

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

a photo is worth a thousand words.

What is lightning?

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

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

what exactly is a ‘surge’ protector?

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

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

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

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

This one hit behind the barn.

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

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

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

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

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

Edit 2024–10.

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.

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

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

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.

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

He then describes Rainy Season and Lightning.

Upvotes:

He then describes the function of a fuse.

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

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

At least they know the answer if they wanted it.

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

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.

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

There are two important concepts here.

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

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.

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

There are three different concepts here that are getting confused.
