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?

This is 'the assistant's answer'

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

Why does my crush make me jealous about having a girlfriend?

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

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

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

How does prayer impact those in need? Is there evidence that God intervenes and improves situations based on our prayers, or is it a psychological belief?

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.

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.

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

What kind of person does a narcissist hate?

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

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.

There are three different concepts here that are getting confused.

Is it possible for sisters to have different skin, hair colours, and hair types? E.g. hair= wavy, afro, straight, curly, black, brown, blonde, red. Skin colour: brown, peach, light brown and more.

He then describes the function of a fuse.

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

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

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

Why do many men like women's breasts?

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

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.

What advice would you give to a father of a teenage daughter on how to protect her from boys, dating, and social media? How should fathers discuss these topics with their daughters?

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

Here is a simplified AC power diagram.

There are two important concepts here.

Why do some people enjoy being dominated?

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).

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.

Are INFJs essentially the most introverted type?

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

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

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

Have you ever been forced into bestiality?

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.

A circuit breaker is similar, but is resettable.

But it can get overloaded, and no longer works.

He then asserts :

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

At least they know the answer if they wanted it.

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

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.

One

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

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

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.

The other is “what does a “fuse” do?”

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

Barnstars:

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.

what exactly is a ‘surge’ protector?

First Sentence:

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.

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

What is lightning?

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.

(Dc diagram shown, AC is similar).

He then describes Rainy Season and Lightning.

“ 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”

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

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

so, what happens?

a photo is worth a thousand words.

This device then solves the entire problem.

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

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

2024–10–16 [ OO OLAOYE OYEBODE ]

I post the exact comment here.

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

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

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