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

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.

There are three different concepts here that are getting confused.

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

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

He then describes the function of a fuse.

In schematic diagrams this is the symbol for a fuse:

what exactly is a ‘surge’ protector?

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

At least they know the answer if they wanted it.

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

This device then solves the entire problem.

He then describes Rainy Season and Lightning.

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

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

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.

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

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

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

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.

I post the exact comment here.

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

Here is a simplified AC power diagram.

What happened to the American Russell Bentley from Texas that was fighting for the pro-Russian commies?

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

What does a fuse do?

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

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

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

First Sentence:

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

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

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

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.

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

A circuit breaker is similar, but is resettable.

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

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

He then asserts :

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.

so, what happens?

There are two important concepts here.

What is lightning?

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

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

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

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

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

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

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

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

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

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

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

This one hit behind the barn.

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

One

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

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

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

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.

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

A fuse is a non-resetable over current circuit 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.

The other is “what does a “fuse” do?”
