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?

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

a photo is worth a thousand words.

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

There are three different concepts here that are getting confused.

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

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

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

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

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

He then describes the function of a fuse.

Why do older siblings always hate younger siblings?

A circuit breaker is similar, but is resettable.

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.

First Sentence:

“ 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”

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

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.

Kquorans, can you please write a story?

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.

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

so, what happens?

There are two important concepts here.

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

Can people who have never met you tell if you are a covert narcissist?

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

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

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

What was the most challenging shift you experienced as an ER physician? Can you describe the details and reasons behind it?

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

But it can get overloaded, and no longer works.

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

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

Edit 2024–10.

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

This is 'the assistant's answer'

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

[image of Common-mode choke]

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

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

(Dc diagram shown, AC is similar).

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

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

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.

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.

At least they know the answer if they wanted it.

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

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

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

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

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

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.

In schematic diagrams this is the symbol for a fuse:

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.

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

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

The other is “what does a “fuse” do?”

2024–10–16 [ OO OLAOYE OYEBODE ]

nine

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

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.

He then describes Rainy Season and Lightning.

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

This one hit behind the barn.

Here is a simplified AC power diagram.

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

He then asserts :

[old diagram got deleted by accident]

What is lightning?

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