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?

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

A circuit breaker is similar, but is resettable.

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

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

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

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.

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

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

How is it, in the USA, a country with 334 million people, the choice of President comes down to two aged men, one of whom is a liar as well as a criminal, one who appears to be on his way to dementia. Surely a democratic country can put up better?

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.

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

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

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

I post the exact comment here.

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

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.

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.

He then describes the function of a fuse.

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

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

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

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

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

Should any books be banned from school libraries? Why is it important for students to read certain books in school?

There are two important concepts here.

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

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.

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

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

But it can get overloaded, and no longer works.

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

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

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

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

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

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

Edit 2024–10.

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.

At least they know the answer if they wanted it.

The other is “what does a “fuse” do?”

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

Upvotes:

He then asserts :

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

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

First Sentence:

This one hit behind the barn.

[image of Common-mode choke]

There are three different concepts here that are getting confused.

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.

Here is a simplified AC power diagram.

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

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

(Dc diagram shown, AC is similar).

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

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

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

This device then solves the entire problem.

what exactly is a ‘surge’ protector?

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

In schematic diagrams this is the symbol for a fuse:

“ 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”
