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?

Here is a simplified AC power diagram.

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

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

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

He then describes the function of a fuse.

What’s the best way to get over someone you love?

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

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.

A circuit breaker is similar, but is resettable.

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

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

Can you tell me something about yourself?

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.

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

Did you ever receive genuine remarks from a medium regarding your deceased relative with information that the medium could never normally know?

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.

This device then solves the entire problem.

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.

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

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

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

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

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

Should women be allowed in “combat roles” within the military?

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

so, what happens?

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

Trump always acts like he was forced to be president, that he was chosen by God. Why do we put up with this? This maniac can't focus and get his mind off of being asskissed like an emperor.

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.

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

I post the exact comment here.

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

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

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

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

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

Barnstars:

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

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

This one hit behind the barn.

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

Edit 2024–10.

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”

First Sentence:

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

But it can get overloaded, and no longer works.

(Dc diagram shown, AC is similar).

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

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

There are two important concepts here.

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

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

There are three different concepts here that are getting confused.

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

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

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

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

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

a photo is worth a thousand words.

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

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

At least they know the answer if they wanted it.

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

What does a fuse do?

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.

He then describes Rainy Season and Lightning.

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