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?

He then describes Rainy Season and Lightning.

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

This device then solves the entire problem.

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

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.

I post the exact comment here.

🔥Why has Prime Narendra Modi become Extremely FRUSTRATED and Highly DEPRESSED because he has NOT been invited by Donald Trump to witness his Oath Ceremony for his INAUGURATION on 20th January as the next PRESIDENT of USA? Does the DESPERATE Narendra Modi FEAR that Donald Trump's actions may even LEAD to the FALL of the BJP-led MINORITY Government in India, as such actions have already caused GREAT PANIC in the NDA Coalition?

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

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

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.

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.

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

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

The other is “what does a “fuse” do?”

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

Are Americans really as uneducated and ignorant as portrayed in the media?

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

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

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.

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

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

What is the reason behind some people referring to themselves as "nice guys" instead of simply being nice?

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.

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

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

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.

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

In schematic diagrams this is the symbol for a fuse:

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

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

a photo is worth a thousand words.

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

But it can get overloaded, and no longer works.

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.

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

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

so, what happens?

[old diagram got deleted by accident]

Barnstars:

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

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

He then asserts :

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

At least they know the answer if they wanted it.

He then describes the function of a fuse.

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

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

First Sentence:

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

What does a fuse do?

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 is lightning?

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

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

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

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

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

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

There are three different concepts here that are getting confused.

Here is a simplified AC power diagram.

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.

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%).

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