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?

First Sentence:

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

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

What happens when you get sick in a country with universal healthcare? What's the process like?

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

In schematic diagrams this is the symbol for a fuse:

But it can get overloaded, and no longer works.

Do Marines really not need sleep during combat training or in general? If this is true, how and why is this possible?

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

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 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 did Farrah Fawcett die?

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

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

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.

What's wrong with white women?

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.

What do you think of the 2 female 18 and 19 year-old German tourists, detained in Honolulu, strip-searched, put in green jumpsuits, placed in a holding cell and the next day deported, for the terrible crime of not pre-booking a hotel for their trip?

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

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 “.

What factors contributed to The Beatles' bitterness?

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

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

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

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.

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

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

Whats the rule that makes "please" pronounced the same as "pleas"?

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.

There are three different concepts here that are getting confused.

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

How do I build rapport with anybody?

a photo is worth a thousand words.

This device then solves the entire problem.

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

Why is Taylor Swift re-recording her albums?

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

He then asserts :

so, what happens?

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

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

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

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.

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

A circuit breaker is similar, but is resettable.

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

what exactly is a ‘surge’ protector?

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.

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

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

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

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

At least they know the answer if they wanted it.

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

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

This is 'the assistant's answer'

There are two important concepts here.

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

What is lightning?

What does a fuse do?

He then describes Rainy Season and Lightning.

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

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

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

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

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