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?

I post the exact comment here.

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

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

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

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

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

what exactly is a ‘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”

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

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.

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.

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

What was your first impression of The Carter V by Lil Wayne? Did it feel like 2008 Wayne, when you heard the first few songs.

A circuit breaker is similar, but is resettable.

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

At least they know the answer if they wanted it.

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

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

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

What is the experience of wearing a school uniform every day? Do people typically get used to it or dislike it?

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

The other is “what does a “fuse” do?”

He then describes the function of a fuse.

What does a fuse do?

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.

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.

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

Here is a simplified AC power diagram.

He then describes Rainy Season and Lightning.

He then asserts :

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

There are three different concepts here that are getting confused.

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

so, what happens?

But it can get overloaded, and no longer works.

(Dc diagram shown, AC is similar).

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.

Barnstars:

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

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

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

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

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

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

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

This device then solves the entire problem.

Edit 2024–10.

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

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

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

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

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

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.

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

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

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