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 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?

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

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

Why do men like to suck another man’s dick?

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

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

Why don't I get sleep at nights?

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

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

He then describes Rainy Season and Lightning.

In schematic diagrams this is the symbol for a fuse:

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

At least they know the answer if they wanted it.

This device then solves the entire problem.

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

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

This is 'the assistant's answer'

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

The other is “what does a “fuse” do?”

Why would Trump make conspiracy claims that Haitians are eating pets in Ohio?

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

There are two important concepts here.

There are three different concepts here that are getting confused.

Did Muhammad Ali ask Dundee to cut his gloves off before Eddie Futch stopped the fight in Thrilla in Manila?

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

I post the exact comment here.

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

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

so, what happens?

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

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 bolt then partially travels down the line to your home.

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

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

My boyfriend wants to break up over too many petty arguments. To me, they are molehills because I truly love him & don't really think twice about them. If he loved me would he work through it?

A circuit breaker is similar, but is resettable.

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

Here is a simplified AC power diagram.

Do all you people that took the "jab" feel lied to yet?

“ 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”

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.

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.

[old diagram got deleted by accident]

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

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.

What is lightning?

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

This one hit behind the barn.

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

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

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

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

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

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.

Barnstars:

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

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.

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

what exactly is a ‘surge’ protector?

He then asserts :

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

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.

But it can get overloaded, and no longer works.

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

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

(Dc diagram shown, AC is similar).

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

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

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

First Sentence:

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

eight

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.

He then describes the function of a fuse.
