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 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.

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

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

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

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.

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

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

“ 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”

But it can get overloaded, and no longer works.

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

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

so, what happens?

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

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.

I'm pretty sure that my dog is transgender, how would I go about transitioning it?

There are two important concepts here.

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

How will the 2026 delimitation affect India as a whole keeping the new count of 888 seats in mind (not the current 543)? I’m looking for genuine answers with facts and not rhetoric. I will only listen to answers and not reply to any of them.

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.

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

(Dc diagram shown, AC is similar).

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.

Upvotes:

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

Have you ever met someone and something seemed so unusual about them but you couldn't put your finger on what it was?

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

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

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

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

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

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

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

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

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

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

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

What is lightning?

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.

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

a photo is worth a thousand words.

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

what exactly is a ‘surge’ protector?

I post the exact comment here.

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

What does a fuse do?

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

Here is a simplified AC power diagram.

In schematic diagrams this is the symbol for a fuse:

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

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

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

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.

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

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

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