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?

This is 'the assistant's answer'

He then asserts :

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

What are scads fish? What types are there?

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

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

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

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

The other is “what does a “fuse” do?”

What do feminists mean when they say they want to ‘normalize’ menstruation and its discussion?

There are three different concepts here that are getting confused.

There are two important concepts here.

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

Short story writers, what is your favorite character you've created and do they appear in more than one of your works?

Barnstars:

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.

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

A protestant (one that adheres to sola scriptura) disagrees with a catholic. How do they propose resolving the dispute?

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

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

He then describes Rainy Season and Lightning.

This one hit behind the barn.

Isn’t freedom of speech and expression an absolute right?

(Dc diagram shown, AC is similar).

This device then solves the entire problem.

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

Why do men cheat on their wives with someone extremely unattractive?

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

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

“ 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”

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

How much does a doctor earn in Sweden per month?

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

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

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.

Why do I randomly start sweating a lot in public (while waiting in line, in a new class, etc.) then start sweating more because I’m embarrassed that I’m sweating so much? Is this social anxiety?

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

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.

Here is a simplified AC power diagram.

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

Have you ever accidentally found out that you were about to be fired?

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.

“ … 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.”

Why do most men who date ugly women brag like it's some big accomplishment, when any guy can pull an ugly woman?

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

But it can get overloaded, and no longer works.

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

what exactly is a ‘surge’ protector?

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

A circuit breaker is similar, but is resettable.

He then describes the function of a fuse.

so, what happens?

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

What does a fuse do?

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

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.

In schematic diagrams this is the symbol for a fuse:

I post the exact comment here.

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.

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

What is lightning?

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

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

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

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

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

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

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

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

Upvotes:

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.

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

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

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

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

At least they know the answer if they wanted it.

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