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.

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

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

What are your thoughts on the trend of Americans labeling themselves as "TikTok refugees" and migrating to the Chinese social media platform RedNote (Xiaohongshu)?

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.

so, what happens?

This one hit behind the barn.

This device then solves the entire problem.

“ 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”

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

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

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

What does a fuse do?

(Dc diagram shown, AC is similar).

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.

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

Upvotes:

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

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.

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.

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

what exactly is a ‘surge’ protector?

In schematic diagrams this is the symbol for a fuse:

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

What are the potential economic consequences of the U.S. following Europe's lead on climate policies, as discussed in the article?

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

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.

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

What causes tension between liberals and conservatives? Is it purely based on ideological differences or are there other factors at play?

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

As a NATO/Ukraine supporter, since you're so blown away and angered by Trump putting Zelensky in his place yesterday, why don't you support the Ukraine by joining the Ukrainian army? There's 200,000,000+ of you. Put your money where your mouths are.

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

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

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

One

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

He then describes Rainy Season and Lightning.

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

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

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

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

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

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.

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

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

I post the exact comment here.

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

At least they know the answer if they wanted it.

This is 'the assistant's answer'

There are two important concepts here.

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

What is lightning?

But it can get overloaded, and no longer works.

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

He then asserts :

There are three different concepts here that are getting confused.

eight

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

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

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

He then describes the function of a fuse.

[old diagram got deleted by accident]

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

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

First Sentence:

A circuit breaker is similar, but is resettable.

Here is a simplified AC power diagram.

The other is “what does a “fuse” do?”

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.

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

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.

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

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

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

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