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

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

What does a fuse do?

How can Democrats not feel hypocritical when they urge Trump not to be vengeful should be become president when the Democrats are trying to put Trump into prison?

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

I post the exact comment here.

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

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

Upvotes:

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

The other is “what does a “fuse” do?”

There are three different concepts here that are getting confused.

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

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

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

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

Ok, so this is a question seeking an answer to clear up whatever gymnastics are in my head. I'm a moderately attractive guy, sincere heart, genuinely looking to love another, established. Why don't women that I'm attracted to, want me back?

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

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

“ 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”

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.

Here is a simplified AC power diagram.

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.

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.

This device then solves the entire problem.

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

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.

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, what happens?

There are two important concepts here.

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

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).

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

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.

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

This is 'the assistant's answer'

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

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

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

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

At least they know the answer if they wanted it.

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

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

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.

He then describes the function of a fuse.

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

He then describes Rainy Season and Lightning.

First Sentence:

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

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

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.

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