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?

What does a fuse do?

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

Atheists who said that reading the Bible made them an atheist, how? Literally there are millions of people who read the Bible daily and still believe in God. So why say that? I mean unless you want to sound smart & edgy

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

I’ve a dismissive avoidant partner who said that he’s overwhelmed by our relationship and that he wants to break up, how do I get him back?

He then asserts :

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

so, what happens?

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

There are three different concepts here that are getting confused.

He then describes the function of a fuse.

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

Barnstars:

Why cant I sleep even tho I am sleepy? I am not anxious or worried but my body just doesn't want to. I've been awake for almost 2 days and feel sleepy but I cant sleep. My doctor said its anxiety related but its not. Is this normal?

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

This one hit behind the barn.

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 fuse is a non-resetable over current circuit protector.

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

Is something wrong with my discharge? So, when I masturbate, white discharge comes from my vagina, but it's not stretchy, it's pasty. It doesn't smell and I'm not itchy, so I'm sure it's not a yeast infection. Why is it pasty though?

“ 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”

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

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

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?

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

At least they know the answer if they wanted it.

What is one small habit that has transformed your life in unexpected ways?

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

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

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

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

Here is a simplified AC power diagram.

In my experience, British people are fat, ugly and arrogant. Why is it and can it be changed?

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

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

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.

Upvotes:

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

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

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

Edit 2024–10.

There are two important concepts here.

what exactly is a ‘surge’ protector?

The other is “what does a “fuse” do?”

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

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

But it can get overloaded, and no longer works.

One

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.

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

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

He then describes Rainy Season and Lightning.

This is 'the assistant's answer'

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

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

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

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

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.

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

I post the exact comment here.

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.

A circuit breaker is similar, but is resettable.

This device then solves the entire problem.

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

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.

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

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

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

What is lightning?

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