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?

At least they know the answer if they wanted it.

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

What real evidence is there to believe in legends such as the story of Atlandida or the lost continent of Lemuria?

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

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).

How was your JEE Mains 2024 April attempt?

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.

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

Why are Democrats at Q so desperate that they keep taking down my links to comments that prove the residents in Ohio have been filing complaints about the Haitians eating the local wildlife from ponds in the local parks? Election interference

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

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.

“ 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”

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

The other is “what does a “fuse” do?”

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

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

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

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

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

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

Why is the First Amendment referred to as a right to free speech instead of an immunity from punishment for one's words, regardless of their truthfulness?

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.

I post the exact comment here.

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.

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

so, what happens?

My landlord just sold the house I’m renting from her. She included all fixtures, that I bought and installed. Does she have this right?

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

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

What happens to single guys when they get older?

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

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

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

What is lightning?

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

Why do people stop working towards achieving their dreams?

There are three different concepts here that are getting confused.

What does a fuse do?

Barnstars:

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

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

Can the fuse protect the electronic devices from lightning instead of 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.

He then describes the function of a fuse.

2024–10–10[John johnson John Johnson ]

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

But it can get overloaded, and no longer works.

A circuit breaker is similar, but is resettable.

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

Edit 2024–10.

In schematic diagrams this is the symbol for a fuse:

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

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

Here is a simplified AC power diagram.

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.

(Dc diagram shown, AC is similar).

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.

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

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

He then describes Rainy Season and Lightning.

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

There are two important concepts here.

He then asserts :

One

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

This device then solves the entire problem.

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

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.
