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?

In schematic diagrams this is the symbol for a fuse:

There are three different concepts here that are getting confused.

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

Barnstars:

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

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

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

But it can get overloaded, and no longer works.

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

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 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.

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

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

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

What was the craziest place that you had sex with someone in public?

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.

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

Here is a simplified AC power diagram.

What are some questions obviously just asked for sexual gratification?

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

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

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

I post the exact comment here.

This device then solves the entire problem.

Why do Trump supporters believe Trump should deport the immigrants? These people you call "illegal immigrants" have lived here for many years, they have houses, jobs, how can you think they will just go back to their country, where they have nothing?

At least they know the answer if they wanted it.

This is 'the assistant's answer'

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

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

There are two important concepts here.

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

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

a photo is worth a thousand words.

“ 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”

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

[old diagram got deleted by accident]

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.

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

What does a fuse do?

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

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

What is lightning?

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

He then describes the function of a fuse.

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

He then describes Rainy Season and Lightning.

He then asserts :

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

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

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.

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

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

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

(Dc diagram shown, AC is similar).

so, what happens?

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.

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

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

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

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

A circuit breaker is similar, but is resettable.

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.

This one hit behind the barn.

what exactly is a ‘surge’ protector?

The other is “what does a “fuse” do?”

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

Upvotes:

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

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

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

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