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?

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

He then describes the function of a fuse.

First Sentence:

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

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.”

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

This one hit behind the barn.

Does being poor build better character than being born rich?

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

what exactly is a ‘surge’ protector?

He then asserts :

When was the first time you felt discriminated against because you were female?

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

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

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

Why is my elder sister so mean?

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

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

“ 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”

How do professional musicians handle their equipment during gigs? Do they bring their own or use the venue's sound system?

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

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

There are three different concepts here that are getting confused.

What was your first experience like with a black man?

At least they know the answer if they wanted it.

I’m running away I live in Indiana what states near by are safe I’m 12 no comments?

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

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.

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

Why are people so terrified or bothered that a person has original creative ideas, hobbies or unique interests?

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

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

What is lightning?

There are two important concepts here.

Edit 2024–10.

One

The other is “what does a “fuse” do?”

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.

(Dc diagram shown, AC is similar).

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

[image of Common-mode choke]

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

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

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

[old diagram got deleted by accident]

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

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

A circuit breaker is similar, but is resettable.

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

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

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

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.

What does a fuse do?

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

a photo is worth a thousand words.

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

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

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

eight

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.

This is 'the assistant's answer'

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.

Here is a simplified AC power diagram.

But it can get overloaded, and no longer works.

OK, this is Mohan Rajaratnam’s definition 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.

so, what happens?

He then describes Rainy Season and Lightning.

This device then solves the entire problem.

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

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

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

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

I post the exact comment here.

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

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

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.

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