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?

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

But it can get overloaded, and no longer works.

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

What is lightning?

At least they know the answer if they wanted it.

This device then solves the entire problem.

Have you ever had a weird experience immediately following the death of a loved one that made you think there is an afterlife and that the deceased person was communicating with you?

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.

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.

Is crossdressing being a transvestite?

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

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

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

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

There are two important concepts here.

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

How do you find out who your handler is as a targeted individual?

This one hit behind the barn.

There are three different concepts here that are getting confused.

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.

Here is a simplified AC power diagram.

“ 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”

This is 'the assistant's answer'

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

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

He then describes Rainy Season and Lightning.

What would TERFs do if there weren't such a thing as being transgender? Who would be their target?

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.

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

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

Do you believe that social media companies should allow posts spreading misinformation about election results, as suggested by Rep. Jim Jordan?

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

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

Why does my girlfriend keep asking me if I love her?

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

(Dc diagram shown, AC is similar).

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

Is it ok to be spanked by your parents if you are not in bed in your set bedtime?

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

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

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

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

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

What does a fuse do?

I post the exact comment here.

eight

A circuit breaker is similar, but is resettable.

The other is “what does a “fuse” do?”

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

so, what happens?

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

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

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

First Sentence:

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.

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

what exactly is a ‘surge’ protector?

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

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.

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

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.

2024–10–14 [Omar Gharbi Omar Gharbi ]

a photo is worth a thousand words.

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

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.

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

He then describes the function of a fuse.

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