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?

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.

What does a fuse do?

what exactly is a ‘surge’ protector?

Why did we evolve to have so many nerve endings in our anuses?

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

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.

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 do you think of a parent telling their adult child to “keep their personal life to themselves” in relation to talking to them? No reason they should say that it was mean what should I do?

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

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

Have you ever had a weird experience immediately following the death of a loved one that made you think there is an afterlife and that the deceased person was communicating with you?

There are two important concepts here.

(Dc diagram shown, AC is similar).

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.

🔥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?

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

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

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

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

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

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

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

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

This device then solves the entire problem.

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

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

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.

This one hit behind the barn.

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

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

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

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

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.

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

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

This is 'the assistant's answer'

The other is “what does a “fuse” do?”

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”

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

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

He then describes the function of a fuse.

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

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

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

First Sentence:

Here is a simplified AC power diagram.

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

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

In schematic diagrams this is the symbol for a fuse:

There are three different concepts here that are getting confused.

so, what happens?

He then describes Rainy Season and Lightning.

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

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

A circuit breaker is similar, but is resettable.

What is lightning?

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.

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

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

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.

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

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

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

At least they know the answer if they wanted it.

I post the exact comment here.

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

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

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

But it can get overloaded, and no longer works.

Barnstars:

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