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?

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

Here is a simplified AC power diagram.

But it can get overloaded, and no longer works.

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

What is lightning?

I told my 13-year-old daughter that she should never start a fight, but has my permission to end it. She got suspended for ending a fight that some other girl picked with her by hitting her then retreating. How do I handle the school’s response?

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

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.

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

Can you tell me a depressing story?

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

This is 'the assistant's answer'

This device then solves the entire problem.

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

“ 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”

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

[old diagram got deleted by accident]

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 photo is worth a thousand words.

What is a good investment portfolio for someone starting in their 20s? 90% VT and 10% BND for a Roth IRA then 100% TDF for a 401k?

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

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

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

He then describes the function of a fuse.

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.

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

Why has Biden pulled ahead in battleground states and is now projected to win the 2024 presidency?

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

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.

He then describes Rainy Season and Lightning.

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

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

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

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

A circuit breaker is similar, but is resettable.

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

At least they know the answer if they wanted it.

Edit 2024–10.

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

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

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.

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

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

One

In schematic diagrams this is the symbol for a fuse:

This one hit behind the barn.

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

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

He then asserts :

There are two important concepts here.

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

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

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

(Dc diagram shown, AC is similar).

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

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

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

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

There are three different concepts here that are getting confused.

What does a fuse do?

Upvotes:

so, what happens?

Barnstars:

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.

what exactly is a ‘surge’ protector?

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

I post the exact comment here.

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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

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

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

First Sentence:

2024–10–16 [ OO OLAOYE OYEBODE ]

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.

The other is “what does a “fuse” do?”

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