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?

Upvotes:

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

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

Why do Argentinians use "vos" instead of "tú" in informal speech?

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.

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

There are two important concepts here.

There are three different concepts here that are getting confused.

I post the exact comment here.

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

Can someone write me a sex story?

(Dc diagram shown, AC is similar).

“ 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”

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

What are some other ways to say "you're welcome" in French besides "de rien"?

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

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

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

What happens when you get sick in a country with universal healthcare? What's the process like?

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

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.

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

What great song was "ruined" once you really listened to the lyrics?

This one hit behind the barn.

He then describes the function of a fuse.

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

Does Donald Trump have low self-esteem?

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

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.

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

What made you recently say to yourself, “Wait. Really?”

A circuit breaker is similar, but is resettable.

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

Will my 9 year old face more difficulties than most girls her age if she’s an early bloomer? My daughter already needs regular B cup bras. The doctor says that my daughter will be even more developed by 11-12 years of age.

What is lightning?

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

Here is a simplified AC power diagram.

How do you recognize when your mental health might need attention?

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.

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

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

This device then solves the entire problem.

what exactly is a ‘surge’ protector?

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

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

Edit 2024–10.

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

What does a fuse do?

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

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.

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

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

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

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

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

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

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

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

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

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

At least they know the answer if they wanted it.

He then asserts :

In schematic diagrams this is the symbol for a fuse:

He then describes Rainy Season and Lightning.

so, what happens?

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

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.

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

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

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

First Sentence:

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

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

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.

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

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

The other is “what does a “fuse” do?”

This is 'the assistant's answer'

a photo is worth a thousand words.

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

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