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?

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

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

Why do liberals think it is okay to steal votes while the rest of us obey the law(s)?

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

This device then solves the entire problem.

He then describes the function of a fuse.

Are you worried that the 2024 US presidential election will result in a close race?

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 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”

Why are people outraged over Latina actress, Rachel Zegler, being cast to play Snow White in the live action remake of Disney’s Snow White and the Seven Dwarfs?

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.

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

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

Moderate liberals, if any use leftist Quora, how do you feel about being associated with those who enjoy burning American flags, supporting Hamas, having men competing against women in sports, open borders, green new deal and general wokery?

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

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

I post the exact comment here.

Can you share a lesson that you learned later in life and how it has impacted your current lifestyle, mentality, or attitude?

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

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

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

(Dc diagram shown, AC is similar).

A circuit breaker is similar, but is resettable.

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

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

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

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

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

First Sentence:

Why is the covert narcissist actively avoiding me when they see me everyday?

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

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.

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.

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

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

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

But it can get overloaded, and no longer works.

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

What is lightning?

At least they know the answer if they wanted it.

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

so, what happens?

What does a fuse do?

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.

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

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

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

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

a photo is worth a thousand words.

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

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

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

In schematic diagrams this is the symbol for a fuse:

This is 'the assistant's answer'

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

This one hit behind the barn.

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 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.

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

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

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

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

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 Rainy Season and Lightning.

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

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

There are three different concepts here that are getting confused.

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

what exactly is a ‘surge’ protector?

The other is “what does a “fuse” do?”

There are two important concepts here.

Edit 2024–10.

Barnstars:

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

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