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?

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

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.

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

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

He then describes Rainy Season and Lightning.

This device then solves the entire problem.

Why is only the left side of my vagina bleeding, on and off?

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

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

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

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

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

He then describes the function of a fuse.

what exactly is a ‘surge’ protector?

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.

He then asserts :

What is the best case of “You just picked a fight with the wrong person” that you've witnessed?

I post the exact comment here.

This one hit behind the barn.

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.

How did you know you weren't the narc?

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.

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

At least they know the answer if they wanted it.

When was you wife swapping fantasy started?

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

The other is “what does a “fuse” do?”

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

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

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

Why do I smell bad even though I have good hygiene?

[old diagram got deleted by accident]

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

What does a fuse do?

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

In schematic diagrams this is the symbol for a fuse:

Which current F1 drivers should switch teams based on historical patterns?

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.

“ 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”

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

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

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

One

There are two important concepts here.

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

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.

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

This is 'the assistant's answer'

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

Here is a simplified AC power diagram.

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

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.

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?".

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

[image of Common-mode choke]

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

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

There are three different concepts here that are getting confused.

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

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

Edit 2024–10.

First Sentence:

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

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.

But it can get overloaded, and no longer works.

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

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

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

a photo is worth a thousand words.

What is lightning?

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

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

A circuit breaker is similar, but is resettable.

so, what happens?

(Dc diagram shown, AC is similar).

Upvotes:

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

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

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