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

What is lightning?

What misfortune led to an important discovery?

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.

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

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

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

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

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

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.

A circuit breaker is similar, but is resettable.

The other is “what does a “fuse” do?”

Why cant school buses ditch kids who are late to the bus at the school? Like on the way home, if a kid is late when all the others arrived to the bus on time, why cant they leave the late kid behind since its not fair to the on time kids to wait?

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

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

There are two important concepts here.

so, what happens?

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

Here is a simplified AC power diagram.

Do older women know what they want?

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

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

Edit 2024–10.

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

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

This device then solves the entire problem.

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

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

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

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

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.

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

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

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

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

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

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.

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

He then describes Rainy Season and Lightning.

At least they know the answer if they wanted it.

What does a fuse do?

“ 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”

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

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

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

First Sentence:

In schematic diagrams this is the symbol for a fuse:

a photo is worth a thousand words.

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

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

He then asserts :

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

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.

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

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.

(Dc diagram shown, AC is similar).

But it can get overloaded, and no longer works.

This one hit behind the barn.

There are three different concepts here that are getting confused.

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 I think this circuit , shows a few more pieces.

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

Barnstars:

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

He then describes the function of a fuse.

I post the exact comment here.

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