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?

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

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

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

Any straight men had a gay experience in the past? What was it and how did you feel?

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

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

Who has experienced what they called a happy accident (bestiality)?

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

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.

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

There are three different concepts here that are getting confused.

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

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

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

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

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

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.

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

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

This one hit behind the barn.

so, what happens?

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

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

2024–10–10[John johnson John Johnson ]

The other is “what does a “fuse” do?”

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.

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

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

I post the exact comment here.

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

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

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

He then asserts :

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

He then describes Rainy Season and Lightning.

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

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

2024–10–16 [ OO OLAOYE OYEBODE ]

(Dc diagram shown, AC is similar).

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.

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

What does a fuse do?

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

Barnstars:

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

what exactly is a ‘surge’ protector?

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

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

a photo is worth a thousand words.

This is 'the assistant's answer'

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

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.

“ 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”
