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?

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

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.

A circuit breaker is similar, but is resettable.

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

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

The other is “what does a “fuse” do?”

Why do Americans and foreigners alike describe the USA as prudish? Why do I see nothing prudish about the USA society? USA feels like one of the loosest countries although Americans claim to be very reserved.

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

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.

so, what happens?

Why did Lord Shiva lust after Mohini - how can he be the supreme and worthy of devotion if he did such a thing?

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

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.

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

What does a fuse do?

He then describes the function of a fuse.

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

There are two important concepts here.

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

I’m wondering about attachment and transference with the therapist and the idea of escape and fantasy? How much do you think your strong feelings, constant thoughts, desires to be with your therapist are a way to escape from your present life? I wonder if the transference serves another purpose than to show us our wounds and/or past experiences, but is a present coping strategy for managing what we don’t want to face (even if unconsciously) in the present—-current relationships, life circumstances, etc. Can anyone relate to this concept of escape in relation to their therapy relationship? How does this play out for you?

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.

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

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

Why am I always so tired and I don't eat enough?

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.

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.

This one hit behind the barn.

[old diagram got deleted by accident]

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

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

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

First Sentence:

Here is a simplified AC power diagram.

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

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

nine

(Dc diagram shown, AC is similar).

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

“ 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?".

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

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

At least they know the answer if they wanted it.

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

a photo is worth a thousand words.

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

“ 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”

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

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

There are three different concepts here that are getting confused.

2024–10–16 [ OO OLAOYE OYEBODE ]

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

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

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

what exactly is a ‘surge’ protector?

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

This is 'the assistant's answer'

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

What is lightning?

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

In schematic diagrams this is the symbol for a fuse:

But it can get overloaded, and no longer works.

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

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

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

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

This device then solves the entire problem.

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

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

He then asserts :

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.

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

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

He then describes Rainy Season and Lightning.
