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%).

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

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

If we do not know the name of the father of a child, e.g. a foundling, an illegitimate, etc., then to whom should the bin or the binti of the child's name be applied?

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

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

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.

If there is an abandoned house with no owner, can I live in it?

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.

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

He then describes the function of a fuse.

How can I get over a break up?

But it can get overloaded, and no longer works.

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.

Edit 2024–10.

Why do people mourn when their leaders lose elections? Is it common for people to cry over events that are out of their control?

He then describes Rainy Season and Lightning.

There are three different concepts here that are getting confused.

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

What are some hard truths that MAGA needs to hear?

In schematic diagrams this is the symbol for a fuse:

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

At least they know the answer if they wanted it.

Can we see your heels?

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

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

How can you tell if someone or someone's is trying to recruit or at least test you for a secret organization?

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

First Sentence:

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

How do you know when your skirt is too short?

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

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.

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

Do all rocket engines emit harmful gases into the atmosphere during launch?

eight

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

There are two important concepts here.

Do you agree with Michael Moore that Donald Trump is "toast" in a political comeback?

This is 'the assistant's answer'

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

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

Can you name an example of bad parenting?

The other is “what does a “fuse” do?”

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

what exactly is a ‘surge’ protector?

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

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

I post the exact comment here.

According to the Gita, how do I abandon fruits of my karma? Should I donate my whole salary and stay hungry?

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

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

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

During the Atlmark incident in 1940, the Brit war criminals violated Norwegian neutrality. Hitler could then justify invading Norway. Have the Brits ever apologized for violating Norwegian neutrality?

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

My son died seven months ago at the age of 24 how do I know if he’s in heaven and can he see me and hear me and why have I not gotten any signs yet from him or Mom just not seeing the signs how do I know if he’s OK how do I know if he’s happy?

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

“ 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 one hit behind the barn.

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

(Dc diagram shown, AC is similar).

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

a photo is worth a thousand words.

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 device then solves the entire problem.

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

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

Here is a simplified AC power diagram.

What does a fuse do?

He then asserts :

Barnstars:

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

so, what happens?

What is lightning?

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.

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

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

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

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

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

A circuit breaker is similar, but is resettable.

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

Upvotes:

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.

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

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