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?

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

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

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 other is “what does a “fuse” do?”

At least they know the answer if they wanted it.

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

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

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

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.

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

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

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

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 are the types of values?

He then describes the function of a fuse.

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

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

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

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

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

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

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

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

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

First Sentence:

eight

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

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

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

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

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

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

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.

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

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

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

what exactly is a ‘surge’ protector?

so, what happens?

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

This device then solves the entire problem.

He then describes Rainy Season and Lightning.

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

There are two important concepts here.

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

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

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

But it can get overloaded, and no longer works.

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

[old diagram got deleted by accident]

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

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

A circuit breaker is similar, but is resettable.

There are three different concepts here that are getting confused.

I post the exact comment here.

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

Here is a simplified AC power diagram.

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.

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

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

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

What is lightning?

This is 'the assistant's answer'
