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?

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

There are two important concepts here.

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.

Is there a correlation between being a medium and mental health?

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

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

What can I do when I'm ugly on both outside and inside? What do I do? Cut myself off from the world to make everyones lives better? I'm a monster. I hurt feelings, and I say what was said to me. I feel like I'm nothing but a burden. What do I do?

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

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

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

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

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

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

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

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

This device then solves the entire problem.

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

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.

There are three different concepts here that are getting confused.

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

What does a fuse do?

He then describes the function of a fuse.

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

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.

In schematic diagrams this is the symbol for a fuse:

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

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.

This one hit behind the barn.

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

At least they know the answer if they wanted it.

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

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

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

He then describes Rainy Season and Lightning.

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

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

“ 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”

what exactly is a ‘surge’ protector?

(Dc diagram shown, AC is similar).

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.

The other is “what does a “fuse” do?”

A circuit breaker is similar, but is resettable.

But it can get overloaded, and no longer works.

Barnstars:

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

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?".

I post the exact comment here.

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

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

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

What is lightning?

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

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

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

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

First Sentence:

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

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

eight

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.

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

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