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?

[old diagram got deleted by accident]

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

At least they know the answer if they wanted it.

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

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

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

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

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

There are three different concepts here that are getting confused.

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

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

What are the reasons for your political affiliation with the Democratic party? What are some aspects of the party that you support and some that you do not?

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

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

so, what happens?

But it can get overloaded, and no longer works.

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.

He then describes the function of a fuse.

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 other is “what does a “fuse” do?”

What are some questions obviously just asked for sexual gratification?

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

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

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

Researchers claim spoof-proof random number generator breakthrough - theregister.com

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 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.

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

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

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

Why are Democrats deflecting and aren’t as tough on Hunter Biden with all of his criminal activity and his rising possibility of him receiving a charge for illegally owing a gun?

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

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.

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 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.

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.

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

This device then solves the entire problem.

He then asserts :

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

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

First Sentence:

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

Barnstars:

In schematic diagrams this is the symbol for a fuse:

“ 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”

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

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

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

A circuit breaker is similar, but is resettable.

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

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

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

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

Here is a simplified AC power diagram.

This one hit behind the barn.

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

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

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

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

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

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

There are two important concepts here.

what exactly is a ‘surge’ protector?

One

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

a photo is worth a thousand words.

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

Edit 2024–10.

I post the exact comment here.
