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?

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

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

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

Do liberals realise that God, who is much more powerful than them, is on the side of Trump?

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

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

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

What smell will you never forget?

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

Here is a simplified AC power diagram.

Why am I dreaming of people I've never seen before?

This device then solves the entire problem.

He then asserts :

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

What is a fun psychological trick to try on someone?

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

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

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

What do most wives fantasize about?

Are fanservice-y characters (i.e. Lara Croft, Tifa Lockhart) immediately bad?

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

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

A circuit breaker is similar, but is resettable.

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

In schematic diagrams this is the symbol for a fuse:

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

There are three different concepts here that are getting confused.

Why cant I breathe when I sleep on my back, I can breathe if im on my side or stomach but I feel uncomfortable since either my neck is twisted or my back is in pain, im physically healthy and my surroundings are clean so whats the problem?

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

Does a narcissist ever get their comeuppance/karma for the vile things they've done? Such as cheating, smear campaign, etc.

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

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

There are two important concepts here.

Do any members of BTS have significant others in real life? If so, why do they choose not to discuss it publicly?

This is 'the assistant's answer'

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

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

What are the most extreme examples of hypocrisy?

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 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.

Which album is your favorite that's now 50 years old (from 1975), and what's the best song on the album?

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.

what exactly is a ‘surge’ protector?

What symptoms did you notice before being diagnosed with cancer?

a photo is worth a thousand words.

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

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

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

What is lightning?

First Sentence:

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

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

What does a fuse do?

eight

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

The other is “what does a “fuse” do?”

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

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.

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

He then describes Rainy Season and Lightning.

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.

“ 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 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.

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.

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

so, what happens?

I post the exact comment here.

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

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

One

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

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

He then describes the function of a fuse.

At least they know the answer if they wanted it.

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

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

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

But it can get overloaded, and no longer works.

(Dc diagram shown, AC is similar).

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

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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.

Barnstars:

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