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?

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

[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?".

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

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.

There are three different concepts here that are getting confused.

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

Why cant I feel anything in my sleep? I cannot even feel myself moving, breathing, and swallowing saliva! I cannot even hear anything, not even my alarm! Some people that I've been with says that I'm moving a lot in my sleep, how can I stop it?

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

What does a fuse do?

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

He then describes Rainy Season and Lightning.

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

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.

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

There are two important concepts here.

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

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

I post the exact comment here.

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

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

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.

a photo is worth a thousand words.

He then describes the function of a fuse.

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

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.

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

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

This one hit behind the barn.

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

what exactly is a ‘surge’ protector?

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

He then asserts :

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

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

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

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

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

This device then solves the entire problem.

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

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

This is 'the assistant's answer'

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

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

In schematic diagrams this is the symbol for a fuse:

A circuit breaker is similar, but is resettable.

At least they know the answer if they wanted it.

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

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

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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

The other is “what does a “fuse” do?”

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

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

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.

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

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

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

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

Barnstars:

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.
