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?

What, when building a house, are the necessary wires (beside 120v) to future proof my house, Cat6, Coax, low voltage, and alarm wires?

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

Why are men today so pussiefied?

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

This device then solves the entire problem.

“ 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”

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

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

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

He then describes Rainy Season and Lightning.

Why is the First Amendment referred to as a right to free speech instead of an immunity from punishment for one's words, regardless of their truthfulness?

But it can get overloaded, and no longer works.

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

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

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.

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

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

What causes tension between liberals and conservatives? Is it purely based on ideological differences or are there other factors at play?

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

so, what happens?

Why are people saying that Trump is fat when he is an athletic 6 foot 3 and 215 pounds?

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

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

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

Why do women consider 80% of men as unattractive?

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

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

There are three different concepts here that are getting confused.

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

what exactly is a ‘surge’ protector?

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

Is there a correlation between being a medium and mental health?

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

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 fuse is a non-resetable over current circuit protector.

The other is “what does a “fuse” do?”

He then asserts :

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

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

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

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

Here is a simplified AC power diagram.

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

First Sentence:

I post the exact comment here.

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

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 circuit breaker is similar, but is resettable.

Barnstars:

There are two important concepts here.

[image of Common-mode choke]

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%).

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

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

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

Upvotes:

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

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

At least they know the answer if they wanted it.

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

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

What does a fuse do?

In schematic diagrams this is the symbol for a fuse:

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

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.

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

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

He then describes the function of a fuse.

[old diagram got deleted by accident]

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

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

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.

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.

This one hit behind the barn.
