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

But it can get overloaded, and no longer works.

Here is a simplified AC power diagram.

He then asserts :

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

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

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.

“ 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”

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.

I just cannot wake up early, even if I sleep on time. What should I do?

At least they know the answer if they wanted it.

What is lightning?

There are two important concepts here.

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

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

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

What does a fuse do?

Is it recommended to leave a note in a lost wallet asking for it to be returned?

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.

Why are liberals so bad at grasping alternative facts? For example, if something doesn’t happen the exact same way Trump described it, liberals dismiss it as false; while conservatives are able to fully understand the underlying principle.

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

This device then solves the entire problem.

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

There are three different concepts here that are getting confused.

First Sentence:

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

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.

He then describes Rainy Season and Lightning.

The other is “what does a “fuse” do?”

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.

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.

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.

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

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

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

This is 'the assistant's answer'

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

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

so, what happens?

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

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

[image of Common-mode choke]

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

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

This one hit behind the barn.

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

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

“ … 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.

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

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

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

I post the exact comment here.

(Dc diagram shown, AC is similar).

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

He then describes the function of a fuse.

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

what exactly is 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.

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.

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

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

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

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

A circuit breaker is similar, but is resettable.

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