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 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”

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

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

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

Why am I so jealous towards couples? Why am I tired of being single and feel my life is over?

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

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

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

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

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

so, what happens?

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.

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 device then solves the entire problem.

Is it possible that my TF caused a kundalini awakening in another person? He is famous because He is a singer. We have not met physically yet, but I have gone through kundalini awakening and DNOTS and their ongoing. I have also had soul recognition so I know for sure that He is my Divine Counterpart and I do not have any doubts about it. But it is indeed perplexing that somebody had an awakening at the physical level because of Him. Is it a test for me? I have a mixture of feelings. On one hand I marvelled at Him and empathised with the person and on the other, I doubt if this just a test for me. I would appreciate your pov. Thank you for much.

At least they know the answer if they wanted it.

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

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

Why is Elon Musk so ugly?

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

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

But it can get overloaded, and no longer works.

What do most wives fantasize about?

[old diagram got deleted by accident]

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

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

I post the exact comment here.

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

What is lightning?

Here is a simplified AC power diagram.

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

What does a fuse do?

He then asserts :

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

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.

First Sentence:

A circuit breaker is similar, but is resettable.

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

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

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

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

Upvotes:

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

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.

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

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

This one hit behind the barn.

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

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

In schematic diagrams this is the symbol for a fuse:

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.

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

Edit 2024–10.

There are three different concepts here that are getting confused.

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

He then describes the function of a fuse.

There are two important concepts here.

(Dc diagram shown, AC is similar).

Barnstars:

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

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

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.

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

a photo is worth a thousand words.

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

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

He then describes Rainy Season and Lightning.

The other is “what does a “fuse” do?”

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

One is “what exactly is in a ‘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.
