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?

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

[old diagram got deleted by accident]

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

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

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.

He then describes the function of a fuse.

Is there a reason why many men give up on dating and relationships? Is the dating scene difficult for them?

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

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

Is a man who enjoys anal sex considered a sissy? For those who think so, why can't they be thought of as someone who enjoys a variety of sexual pleasure?

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

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

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 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.

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 where the MOV conducts again, and dissipated the energy.

But it can get overloaded, and no longer works.

How did you cope when someone you love, dealing with hyper-independence and trauma, felt they needed space to heal alone? Were you able to support them without overstepping, and did you eventually reconnect? How did that journey unfold?

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

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

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

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

what exactly is a ‘surge’ protector?

There are two important concepts here.

What started the whole idea of femboys? What is the whole point of a femboy? Did a boy or a man just randomly start dressing or acting feminine or something?

so, what happens?

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

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

Were the 1980s as uptight and prudish as movies and TV shows make them out to be? When I think of 80s culture, I think about a very "icky" judgmental yuppie status quo time period.

What is lightning?

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.

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

The other is “what does a “fuse” do?”

Why are conservatives banning liberal books? Why are conservatives so offended by the teaching of racism and other topics?

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.

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

Why are you bare-nakedly displaying your anti-Trump bias while ignoring the liberals' destruction of the US? I am now blocking your e-mails because of your biased articles.

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

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

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

If people in the UK hate Trump so much, why does he own golf courses there?

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

There are three different concepts here that are getting confused.

This device then solves the entire problem.

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

He then describes Rainy Season and Lightning.

In schematic diagrams this is the symbol for a fuse:

Edit 2024–10.

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

“ 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”

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

This one hit behind the barn.

A circuit breaker is similar, but is resettable.

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

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

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

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

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

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

This is 'the assistant's answer'

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

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

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

Barnstars:

At least they know the answer if they wanted it.

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.

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

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

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

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

He then asserts :

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

What does a fuse do?

Here is a simplified AC power diagram.

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

a photo is worth a thousand words.

(Dc diagram shown, AC is similar).

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