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?

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

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 is 'the assistant's answer'

Why are fewer English people going to their local pubs for a drink? Are they aware that many pubs are shutting down due to lack of customers?

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

He then describes the function of a fuse.

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

Do people of NYC drive around Central Park all the time? Is there any subway tunnel to cross the park quickly? Is it annoying for people and does it cause traffic?

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

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

Why are right-wing commentators spreading conspiracy theories about Haitians eating local pets in Springfield, Ohio?

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

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

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

This device then solves the entire problem.

He then describes Rainy Season and Lightning.

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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

What is the most heartbreaking or sad love story that you ever had (experienced)?

[old diagram got deleted by accident]

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

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

What are some disadvantages of living in rural areas? What are the advantages?

What is lightning?

A circuit breaker is similar, but is resettable.

In schematic diagrams this is the symbol for a fuse:

What would you do if you found out that someone had broken into your home while you were sleeping?

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

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

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

Why do some men like older women?

Here is a simplified AC power diagram.

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.

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

Why do narcissists avoid talking about the real issues?

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

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.

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

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

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

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

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

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

First Sentence:

so, what happens?

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

Edit 2024–10.

what exactly is a ‘surge’ protector?

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

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

But it can get overloaded, and no longer works.

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 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”

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.

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

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

[image of Common-mode choke]

a photo is worth a thousand words.

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.

There are two important concepts here.

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

The other is “what does a “fuse” do?”

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

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

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

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

Upvotes:

At least they know the answer if they wanted it.

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

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

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

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

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

There are three different concepts here that are getting confused.

(Dc diagram shown, AC is similar).

He then asserts :

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

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

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

What does a fuse do?

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