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?

Edit 2024–10.

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

If Donald Trump is so evil and Joe Biden is so good why is Trump the one selflessly providing Bibles for the needy while Biden doesn't? Why doesn't Biden care for America's spiritually needy people as much as Trump?

What does a fuse do?

How do you feel cockroach?

This is 'the assistant's answer'

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

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

Do crossdressers like wearing pantyliners and tampons in their butts?

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

This device then solves the entire problem.

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

Is there anything you did that you regret? If so, what is it, and why?

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

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

This one hit behind the barn.

what exactly is a ‘surge’ protector?

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

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

Should I have left it alone and kept quiet? I came out as gay to my adult kids last week. Age 61 married 15 years, divorced for 20. I feel so guilty for ruining their lives by living a lie.

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

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

What does it mean if you dream your dad died?

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

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

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

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

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.

What is something you want to "get off your chest"?

He then describes Rainy Season and Lightning.

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

so, what happens?

Do you anal play alone?

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

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

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

There was this one weird Bollywood movie that was released in the 2000s. Amitabh Bachchan was starring with another actress and the story was about how the old guy (Amitabh Bachchan) fell in love with the young woman. What is the name of this movie?

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

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

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.

Why is my coworker suddenly being so mean towards then being nice like nothing happened? She is nice with everyone but me.

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.

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

Upvotes:

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.

“ 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”

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

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

I post the exact comment here.

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

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

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

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

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

A circuit breaker is similar, but is resettable.

What is lightning?

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

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

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

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

First Sentence:

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.

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

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

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

At least they know the answer if they wanted it.

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

a photo is worth a thousand words.

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

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

There are two important concepts here.

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.

Here is a simplified AC power diagram.

(Dc diagram shown, AC is similar).

He then describes the function of a fuse.

He then asserts :

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.

In schematic diagrams this is the symbol for a fuse:

[old diagram got deleted by accident]

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

But it can get overloaded, and no longer works.

The other is “what does a “fuse” do?”

There are three different concepts here that are getting confused.

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