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?

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

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.

What does a fuse do?

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

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).

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

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

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

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

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

A circuit breaker is similar, but is resettable.

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

What would happen if the Soviet Union had simply annexed Manchuria after World War 2 or kept it independent as a puppet state allied them and separate from China as China was too weak too oppose it anyway?

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

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

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

This one hit behind the barn.

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

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

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

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

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

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.

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

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

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

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

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.

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.

I post the exact comment here.

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.

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

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

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

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

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.

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.

There are two important concepts here.

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

This is 'the assistant's answer'

so, what happens?

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

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

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

This device then solves the entire problem.

what exactly is a ‘surge’ protector?

There are three different concepts here that are getting confused.

He then asserts :

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