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?

He then describes Rainy Season and Lightning.

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

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

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

a photo is worth a thousand words.

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

There are two important concepts here.

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

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.

“ 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”

Why is India lagging behind China in economic development when India is a democracy while China isn’t?

What does a fuse do?

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 is 'the assistant's answer'

At least they know the answer if they wanted it.

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

so, what happens?

[old diagram got deleted by accident]

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

Trump is going to target known criminals in the country illegally for deportation. The Democrats have vowed to fight him every step of the way. Don't they understand this is one of the issues that cost them the white house, the house and senate?

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

A circuit breaker is similar, but is resettable.

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.

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

There are three different concepts here that are getting confused.

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

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

Here is a simplified AC power diagram.

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

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

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

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

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

(Dc diagram shown, AC is similar).

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

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

But it can get overloaded, and no longer works.

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

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

This device then solves the entire problem.

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

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.

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

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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.

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.

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

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

The other is “what does a “fuse” do?”

Barnstars:

He then describes the function of a fuse.

One

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

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

what exactly is a ‘surge’ protector?

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.

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

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

I post the exact comment here.

He then asserts :

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

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

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

What is lightning?

In schematic diagrams this is the symbol for a fuse:

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

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

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.

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

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.
