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?

so, what happens?

A circuit breaker is similar, but is resettable.

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

There are three different concepts here that are getting confused.

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

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

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.

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

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.

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

Edit 2024–10.

What explanations do flat earthers have for the shape of our planet? If they do not have any, why should their opinions on this topic be considered credible?

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 it can get overloaded, and no longer works.

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

What do you think hell is like?

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

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

What does a fuse do?

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

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

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.

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.

What is lightning?

Here is a simplified AC power diagram.

He then describes Rainy Season and Lightning.

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

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

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

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

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

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

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

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

The other is “what does a “fuse” do?”

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

what exactly is a ‘surge’ protector?

Barnstars:

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

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.

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

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.

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

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

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

He then describes the function of a fuse.

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

a photo is worth a thousand words.

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.

At least they know the answer if they wanted it.

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

I post the exact comment here.

This one hit behind the barn.

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

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

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

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

This device then solves the entire problem.

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

He then asserts :

“ 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”

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

In schematic diagrams this is the symbol for a fuse:

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

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