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

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

In schematic diagrams this is the symbol for a fuse:

How do I get a white man for a serious relationship?

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.

At least they know the answer if they wanted it.

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

What does it mean when someone says "I'm feeling frisky"?

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

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

Here is a simplified AC power diagram.

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

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

But it can get overloaded, and no longer works.

How do you find out who your handler is as a targeted individual?

A circuit breaker is similar, but is resettable.

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

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

I took a video of my serve (60 FPS) and it took 0.4 seconds from my racket to the service line. How fast would you say my serve was?

what exactly is 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.

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

There are two important concepts here.

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

“ 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”

This one hit behind the barn.

He then describes Rainy Season and Lightning.

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

He then describes the function of a fuse.

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

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

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

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

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

He then asserts :

First Sentence:

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

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

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

so, what happens?

Barnstars:

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

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

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

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

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

2024–10–16 [ OO OLAOYE OYEBODE ]

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.

This device then solves the entire problem.

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

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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

(Dc diagram shown, AC is similar).

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

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

What does a fuse do?

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.

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

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

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

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

The other is “what does a “fuse” do?”

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

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

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.

There are three different concepts here that are getting confused.

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.
